It might also mean RAM-intensive, such as in-memory caching or database servers, or both CPU-intensive and RAM-intensive. Compute-focused cloud specifically that supports compute-intensive workloads. OpenStack controller service that run Image, Identity, and Networking, combined with the support services MariaDB and RabbitMQ. You can deploy a general high availability cloud if you are unsure of specific technical or environmental needs. These architectures must balance a high volume of east-west traffic with north-south traffic to maximize data delivery efficiency. Stores images to be used for booting instances and managing snapshots. Although enterprise storage is not a requirement, many environments include storage that the OpenStack cloud can use as a backend. These application types are sensitive to network jitter and latency. OpenStack is the open source cloud platform that enables Infrastructure as a Service (IaaS). Details include how to configure the OpenStack Cinder storage block service using the Oracle ZFS Storage Appliance to implement multiple OpenStack volume services, each meeting different types of storage SLA requirements. Hardware load balancer provides SSL offload functionality and connects to tenant networks to reduce address consumption. various Networking agents, and the Dashboard. OpenStack 101 with Joshua McKenty from Piston Cloud Computing. In this architecture example, the database I/O requirements are high and demand storage from a fast SSD pool. The web application instances are stateless, so in case one of the instances fails, the application can continue to run. As in the previous case, this architecture supports a combination of OpenStack and Kubernetes services that can be distributed in the environment to fulfill all the required functionality for each site. Hardware-based load balancing cluster for a large-scale Web application. OpenStack Administrator Guides for Pike. For example, most web services applications do not have major issues with a full-mesh overlay network, and some network monitoring tools or storage replication workloads have performance issues with throughput or excessive broadcast traffic. Vertically scale by increasing the capacity of internal compute host components to support usage increases. In a storage-focused architecture, instance density and CPU/RAM over-subscription are lower. This general-purpose architecture can run up to 140 web instances, and the small number of MariaDB instances requires 292 vCPUs and 584 GB RAM. General high-availability cloud to use if you are unsure of specific technical or environmental needs. of two network interfaces. This architecture type uses a cloud backup application, where incoming data to the cloud traffic is higher than the outgoing data. This can also include The OpenStack user requires more information about the underlying network An online classified advertising company wants to run web applications that include Apache Tomcat, Nginx and MariaDB in a private cloud. Measure the consistency with which you deliver services instead of the average speed or capacity of the cloud. Essentially, it routes runs a Networking service agent that connects instances to virtual networks In this case, it is easier to automate the infrastructure to apply the target IP to a new instance, instead of reconfiguring legacy or external systems for each new instance. intended to be used for production system installations, but to create a You can also use filters to customize the Compute scheduler that handles placement in the cells. OpenStack Networking Guide for Queens, In addition, it requires manual replication of some configuration elements, such as flavors, across cells. A split network configuration is compatible with databases that reside on private tenant networks, because the databases do not emit a large quantity of broadcast traffic and might need to interconnect to other databases for content. The OpenStack project has a couple of deployment projects with You should use the same, or similar CPUs in the extra nodes to reduce the chance of breaking any live-migration features. For example, a solution that expands to 50 PB is more expandable than a solution that only expands to 10PB. This metric is related to, but different from, scalability, which is a measure of the solution performance as it expands. Basic authentication and authorization for users and tenants. If your company has an existing Red Hat account, your organization administrator can grant you access. Cloud-based file storage and sharing service, commonly used in OpenStack deployments. A three-node MariaDB and Galera cluster, each with 4 vCPUs and 8 GB RAM. OpenStack's architecture is made up of numerous open source projects. Decide the maximum capacity of the storage solution. However, cells provide the required scale while exposing a single public API endpoint to users. Network configuration affects latency, bandwidth, and distribution of instances. Overlay can also induce enough latency to cause issues with the hypervisor, which causes performance degradation on packet-per-second and connection-per-second rates. Network-Focused Architecture Types, 4.5.2. Web servers are common applications in cloud services, and require an understanding of the network requirements. through a variety of complementary services. Connectivity can affect latency and performance. Matt Kassawara mkassawara at gmail.com Tue Oct 14 15:05:36 UTC 2014. The provider networks option deploys the OpenStack Networking service (routing) services, and advanced services such as infrastructure to create a virtual network to exactly match the specific guides per version: The example architecture requires at least two nodes (hosts) to launch a basic In addition to basic design considerations described in Chapter 3, Design, you should also follow the considerations described in Section 4.4.4, “Storage-Focused Architecture Considerations”. In this example, Ceph provides a Swift-compatible REST interface, as well as block-level storage from a distributed storage cluster. These projects are used to set up OpenStack's undercloud and overcloud —used by sys admins and cloud users, respectively. Graffiti has the initial intent of providing cross service metadata “tagging" and search aggregation for cloud resources. Monitoring and alerting services are critical in cloud environments with high demands on storage resources. If you select a centralized storage array, determine how to connect the hypervisors to the storage array. Workloads in a compute-focused OpenStack cloud generally do not require persistent block storage, except some uses of Hadoop with HDFS. Attribution 3.0 License. This configuration ensures that the load balancer can communicate with the application HTTP servers without consuming a public IP address. In this type of network design, you can add additional bandwidth as well as scale out to additional racks of gear. In some compute-intensive workloads, minimizing the delays that the CPU experiences while fetching data from storage can significantly improve the overall performance of the application. The OpenStack project is provided under the Although a compute-focused cloud does not usually require major data I/O to and from storage, storage performance is still an important factor to consider. supports all types of cloud environments. August 20, 2015 By Lingeswaran R 2 Comments. Alerting and notification of responsible teams or automated systems that can resolve problems with storage as they arise. It is designed to provide a minimum proof-of-concept for the purpose of learning about OpenStack. They should only be used for testing, and should not be deployed in a production environment. Cloud storage typically runs on a virtual infrastructure and resembles broader cloud computing in interface accessibility, elasticity, scalability, multi-tenancy, and metered resources. Compute-focused workloads include the following use cases: A compute-focused OpenStack cloud does not typically use raw block storage services because the cloud does not generally host applications that require persistent block storage. The network must scale out to meet user demand and to deliver web pages with minimum latency. A tour of the ARM architecture and its Linux support - Duration: 46:34. linux conf au 2017 - Hobart, Australia 50,556 views Therefore, this architecture can be used in multiple OpenStack designs. OpenStack. Production environments should implement For more information about OpenStack Networking, see Chapter 2, Networking In-Depth. If a MariaDB instance fails, storage must be re-attached to another instance and re-join the Galera cluster. services and VLAN segmentation of networks. dedicated network nodes. For example, if we choose to use the KVM hypervisor in the OpenStack setup, when the end user submits the virtual machine creation request via the OpenStack … Performance. [OpenStack-docs] Storage node missing in the example architecture? new users of OpenStack with sufficient Linux experience. Big data often uses partial replicas of the data to maintain integrity over large distributed clouds. In cases where regions in a cloud are geographically distributed, you might also use WAN optimization to reduce latency or packet loss. By default, overlays include a secondary full-mesh option that depends on the workload. Therefore, ensure that the network characteristics minimize latency to boost the overall performance of the environment. services such as an SQL database, message queue, and The API cell directs API calls to compute cells using a customized variation of the cell scheduler. This configuration affects the number of power connections and also impacts network and cooling requirements. Think of these as curated playlists of OpenStack configurations. After becoming familiar with basic installation, configuration, operation, Because this service operates primarily as a backup service, most of the traffic moves southbound into the environment. integration. This Reference Architecture can be used as an installation and deployment example for organizations deploying their first RHOS 13 based private cloud. Monitoring of network resources for service disruptions which affect access to storage. and is not intended for production system installations. Performance-focused storage system designed for management and analysis of large data sets, such as Hadoop clusters. You might consider this a storage-focused use case, but the network-side requirements make it a network-focused use case. Manages instance templates to use when scaling out and during traffic bursts. and Optionally, the controller node runs portions of the Block Storage, Object This slideshare explains the architecture of OpenStack. A master node is a system running Oracle Linux and the Oracle OpenStack CLI (kollacli), which is used to deploy OpenStack services to the nodes. You must also consider fault domains and power density. Because this workload includes an externally-facing service and an internally-replicating application, it requires north-south and east-west traffic considerations. Storage-Focused Architecture Considerations, 4.5.1. Running performance tests of local workloads with and without HTT can help determine which option is more appropriate for a particular case. Although more expensive, you can also consider higher density switches as you should not design the network beyond functional requirements. The following cloud-backup application workload has two specific behaviors that impact the network. The Red Hat OpenStack Platform director is a toolset for installing and managing a complete OpenStack environment. For example, disabling HTT can help intense computing environments. Virtual Machines, Images, and Templates, 1.3.2. A compute-focused OpenStack cloud is extremely demanding on processor and memory resources. The decision to enable HTT on a CPU depends on the use case. When users download content, that content moves northbound out of the OpenStack environment. Availability. Compute-intensive workload might mean CPU-intensive, such as significant data computation, encryption, or decryption. Previous message: [OpenStack-docs] Storage node missing in the example architecture? You can measure the storage hardware performance by observing the latency of storage I/O requests. This Reference Architecture will provide an example of an entry level Red Hat OpenStack Platform (RHOSP) 13 p rivate cloud and Ceph Storage deployment on industry leading HPE Synergy servers. These sample configurations are based on OpenStack case studies and real-world reference architectures across industries and workloads. This guide introduces the OpenStack cloud components and provides design guidelines and architecture examples to help you design your own OpenStack cloud. When a user uploads and stores content, that content moves southbound into the OpenStack environment. If you are a new customer, register now for access to product evaluations and purchasing capabilities. OpenStack offers both Block Storage (cinder) and Object Storage (swift). In this example architecture, we will build an OpenStack solution with multiple nodes. Architecture Design Guide. For example on a storage node, Cinder communicates with the storage appliance's API, and it is the storage appliance that performs the storage management. North-south traffic consists of data that moves in and out of the cloud. FWaaS. objects. service policies. This architecture is for a cloud that provides file storage and file-sharing. The controller node requires a minimum of two network interfaces. services such as Block Storage and Object Storage require additional nodes. Environments for long-lived workloads are often larger and more complex, but you can offset the cost of building these environments by keeping them active between jobs. Figure 1 Example of a Multiple Network Architecture. An integrated management console, or other dashboards that visualize SNMP data, helps to discover and resolve issues with the storage cluster. The website generates large amounts of log data every day that need to be archived. openstack Architecture and components overview. Monitoring and reporting for other OpenStack services. Manages templates for instances and block storage volume. Many of these systems must access large, high-performance database backends. Each configuration will give you a good idea of which core and optional … The site.pp.example manifest captures the user-modifiable components and defines the various parameters that must be set to configure the OpenStack cluster, including the Puppet Master and Cobbler setup on the build server. Infrastructure components are not shared, so that the workloads can consume as many available resources as needed. The router and the load balancer use the GRE tunnel ID of the application tenant network, and an IP address that is located in the tenant subnet but outside of the address pool. Cloud Storage and Backup Architecture, 4.5.3. For example, building an application with a redundant micro-services architecture -we’ll see an example shortly- makes the application cloud native, since this architecture allows our application to be deployed in a distributed manner that allows it to be scalable and almost always available. Choose one of the following virtual networking options. The following table lists the requirements for each compute center to add: This architecture uses cells for segregation of compute resources and for transparent scaling between different data centers. It is designed to this page last updated: 2020-12-23 10:37:21, OpenStack Administrator Guides for Queens, Creative Commons All architecture examples in this guide assume that you deploy OpenStack Platform on Red Hat Enterprise Linux 7.2 with the KVM hypervisor. with layer-3 (routing) services that enable Additionally, this option provides the foundation for You can choose this architecture type if you require high performance Compute resources. The environment then copies the results or the artifacts from each instance to long-term storage before it terminates the instances. You can add capacity to your compute environment with one or more of the following strategies: Horizontally scale by adding extra capacity to the cloud. When providing network service for applications such as video streaming or storage replication, configure the OpenStack hardware nodes and the supporting network equipment for jumbo frames wherever possible. This chapter contains references to architecture examples of Red Hat OpenStack Platform deployments. HTT is an Intel proprietary simultaneous multi-threading implementation that is used to improve parallelization on the Intel CPUs. Each node requires a minimum of one Use a load balancer to serve the VIP and also connect to the tenant overlay network with external methods or private addresses. A storage-focused cloud design should include: Section 4.5.1, “Network-Focused Architecture Types”, Section 4.5.4, “Network-Focused Architecture Considerations”. See all LBaaS and Hardware load balancers to distribute workloads or off-load certain functions, External devices to implement dynamic routing. VDI systems are sensitive to network congestion, latency, and jitter. OpenStack Reference Architecture For 100, 300 and 500 Nodes¶. OpenStack Swift Architecture ... For example, if a valid request is sent to Swift then the proxy server will verify the request, determine the correct storage nodes responsible for the data (based on a hash of the object name) and send the request to those servers concurrently. The power and cooling density requirements might be lower with 2U, 3U, or 4U servers than with blade, sled, or 1U server designs. Changing the CPU over-commit ratio can cause conflicts with other nodes that require CPU resources. The basic components that make up the architecture of OpenStack are:Compute (Nova)Compute is one of the most important and mandatory components of OpenStack. The cloud uses a compute cell for each of the two original data centers and will create a new compute cell whenever you add a new data center. Storage, Orchestration, and Telemetry services. In addition, you can implement active queue management to deliver voice and multimedia content. Cloud This slideshare explains the architecture of OpenStack. In this architecture type, OpenStack integrates with Hadoop to manage the Hadoop cluster with Ceph as the storage backend. A shared file system or object store maintains initial data sets and serves as the destination for saving the computational results. The cloud storage model stores data in logical pools on physical storage devices. However, the term can also include other types of data storage that are available as a service. Monitoring and reporting for other OpenStack services. You can use an SSD cache layer to link block devices directly to hypervisors or to instances. In addition to basic design considerations described in Chapter 3, Design and to network node design described in Chapter 2, Networking In-Depth, the following items should be considered for a network-intensive architecture. Monitoring of storage resources, such as available storage, memory, and CPU. Keep your systems secure with Red Hat's specialized responses to security vulnerabilities. Cloud storage is highly fault tolerant with redundancy and data distribution, is highly durable with versioned copies, and can perform consistent data replication. and troubleshooting of these OpenStack services, you should consider the If you deploy storage in the Compute hosts, ensure that the hardware can handle the storage and compute services. For storage, use a scaled-out solution with directly-attached storage in the servers. You can use this architecture type for existing storage environments. For example, ImagePropertiesFilter provides special handling based on the operating system that the guest runs, for example Linux or Windows. Next message: [OpenStack-docs] Usage of several services on one line Messages sorted by: Architecture Design Guide, To ensure that the OpenStack infrastructure components are highly available, nodes use the Pacemaker add-on for Red Hat Enterprise Linux together with HAProxy. High-Performance Database Architecture, 4.4.4. To extend a tunnel beyond the OpenStack regions to another region or to an external system, implement the tunnel outside OpenStack or use a tunnel-management system to map the tunnel or the overlay to an external tunnel. MariaDB server instances store data on shared enterprise storage, such as NetApp or Solidfire. HPC has high east-west traffic patterns for distributed computing within the network, but can also have substantial north-south traffic in and out of the network, depending on the application. Erasure coded pools do not support partial writes. High-speed or high-volume transactional systems. Use the Telemetry service to perform metering for the purposes of adjusting project quotas. NTP. The compute node runs the hypervisor portion of Compute that Consider the self-service networks option below if you desire these features. In addition to basic design considerations described in Chapter 3, Design and to storage node design described in Section 3.3, “Storage Resources”, the following items should be considered for a storage-intensive architecture. The architecture provides prescriptive guidance and in the simplest way possible with primarily layer-2 (bridging/switching) The current environment consists of the following components: The company runs hardware load balancers and multiple web applications that serve the websites. Users are sensitive to latency and jitter fluctuations and can detect them at very low levels. Example cloud storage applications include: For more information about OpenStack storage services, see Section 1.2.2, “OpenStack Object Storage (swift)” and Section 1.2.1, “OpenStack Block Storage (cinder)”. In this example, the architecture uses the Ceph Swift-compatible REST interface that connects to a caching pool and enables acceleration of the available pool. The REST interface can also use the SSD cache systems as an inline cache. If you plan too conservatively, you might experience unexpected over-subscription of the cloud. Network-Focused Architecture Considerations, Section 1.2.2, “OpenStack Object Storage (swift)”, Section 1.2.1, “OpenStack Block Storage (cinder)”, Shared application development environment, Environment requiring scale-out additions instead of than scale-up additions, Between 120 and 140 installations of Nginx and Tomcat, each with 2 vCPUs and 4 GB of RAM. Video conferencing systems have symmetrical traffic pattern, but if the network is not hosted on an MPLS private network, the system cannot use network quality of service (QoS) to improve performance. QoS impacts network-intensive workloads because it provides instant service to packets with high priority because of poor network performance. A compute-focused cloud supports CPU-intensive workloads such as data computation or encryption and decryption, RAM-intensive workloads such as in-memory caching or database servers, or both. services using a functional example architecture suitable for OpenStack Administrator Guides for Rocky. This architecture type is not typically storage-intensive or network-intensive, and serves customers that require the power of Compute resources. If one network component cannot handle jumbo frames, the entire path reverts to the default MTU. Use this service to monitor instance usage and invoke instance templates from the Orchestration service. With this in mind, I thought it would be a good chance to revisit my earlier blog post on OpenStack Compute (“Nova”) architecture. In this situation, you should configure a network to be asymmetrically downstream, because the traffic that enters the OpenStack environment is greater than the traffic that leaves the environment. OpenStack is the open source cloud platform that enables Infrastructure as a Service (IaaS). use cases, or how to determine which architecture is required, see the Define a reference architecture for edge and far edge deployments including OpenStack services and other open source components as building blocks. The storage system uses a LUN backed with a set of SSDs in a traditional storage array, and uses OpenStack Block Storage integration or a storage platform such as Ceph. In applications such as Voice over IP (VoIP), differentiated service code points are usually required for continued operation. Cloud users expect instant access to new resources as needed. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Use solid-state drive (SSD) disks to minimize instance storage latency, reduce CPU delays, and improve performance. Scaling out hypervisor hosts also affects network and other data center resources. In this example, you can expand the architecture further as needed. Environments that support delivery of backend network services such as DNS, NTP, or SNMP. These permutations of perspectives drive a paucity of aligned user stories to share with the OpenStack and StarlingX communities. Consider this increase when you reach rack capacity or if you need additional network switches. security groups. For more information on production architectures for Rocky, see the It is based primarily on the OpenStack project TripleO, which is an abbreviation for “OpenStack-On-OpenStack“.This project takes advantage of OpenStack components to install a fully operational OpenStack environment. www.openstack.org OpenStack Workload Reference Architecture: Web Applications 6 Load balancing Load balancing can be based on round robin, least connections, or random. You can build a storage array using commodity hardware with Open Source software, but you might need specialized expertise to deploy it. The example architecture used in this guide is a minimum configuration, and is not intended for production system installations. Clouds used for the management and collection of big data create significant demand on network resources. It is mostly deployed as infrastructure as a Service(IAaaS) where virtual servers and other resources are made available to customers. It is highly flexible and enables reduced cost of operations with features such as self-healing and auto-balancing. The web application instances run from local storage on each of the Compute nodes. Erasure coded pools require special considerations, such as higher computational requirements and limitations on which operations are allowed on an object. You can also use HAProxy. In addition, some Intel CPUs support Hyper-Threading Technology (HTT), which doubles the core capacity. It is important to select network hardware that supports the required port count, port speed, and port density, and that also allows future growth when workload demands increase. implementation, massive scalability, and a rich set of features. You can use cloud storage services on-premise or off-premises. OpenStack Database-as-a-Service (trove), 1.3. This example architecture differs from a minimal production architecture as Advanced OpenStack Networking Concepts, 2.4.2. Architecture Design Guide, This configuration is recommended for data centers with older infrastructure. In a cloud computing environment, it acts as a controller, which manages all the resources in a virtual environment. Runs in the API cell and maintains a small set of Linux images, onto which orchestration tools can place applications. An example of this is StarlingX, as its architecture closely resembles the distributed model. Big-data analytics using Hadoop or other distributed data stores, Continuous integration or continuous deployment (CI/CD), Signal processing for network function virtualization (NFV). You need more hosts to support the anticipated scale, especially if the design uses dual-socket hardware designs. Environments that run customer-facing network tools to support services. This information can help you model capacity performance and determine the current and future capacity of the cloud. Processes and archives logs from the web application servers. Networking services. This design includes the following components and workflows: A web service architecture can consist of many options and optional components. Automatically deploys and tests new instances. High-performance storage system that assumes increased database IO requirements and utilizes a solid-state drive (SSD) to process data. Storage-Focused Architecture Types, 4.4.3. In this architecture type, OpenStack integrates with Hadoop to manage the Hadoop cluster with Ceph as the storage backend. of underlying infrastructure on the data network. self-service networks using overlay segmentation methods such This option lacks support for self-service (private) networks, layer-3 You should design the network architecture with a scalable network model that helps to add capacity and bandwidth, such as the leaf-spline model. Configure jumbo frames across the entire path that the packets traverse. By avoiding input-output (IO) overhead, you can significantly enhance workload performance. You can use these services for internal network management. Section 4.5.2, “Cloud Storage and Backup Architecture”. A master node is not an OpenStack node.
