openstack example architecture

openstack example architecture

KVM hypervisor. of two network interfaces. dedicated network nodes. It is designed to provide a minimum proof-of-concept for the purpose of learning about OpenStack. OpenStack is a free open standard cloud computing platform, mostly deployed as infrastructure-as-a-service (IaaS) in both public and private clouds where virtual servers and other resources are made available to users. Example environments include financial systems, credit card transaction applications, and trading systems. In this architecture example, the database I/O requirements are high and demand storage from a fast SSD pool. Monitoring of network resources for service disruptions which affect access to storage. objects. service, management portions of Compute, management portion of Networking, Consider enabling HTT to improve the performance of multi-threaded applications. Performance-focused storage system designed for management and analysis of large data sets, such as Hadoop clusters. The current environment consists of the following components: The company runs hardware load balancers and multiple web applications that serve the websites. services such as Block Storage and Object Storage require additional nodes. Networking services. You can use cloud storage services on-premise or off-premises. It is recommended to run OpenStack Object Storage on network connections with 10 GbE or higher. self-service networks using overlay segmentation methods such A three-node MariaDB and Galera cluster, each with 4 vCPUs and 8 GB RAM. For information on creating architectures for specific The OpenStack project is provided under the These architectures depend on a reliable network infrastructure and on services that satisfy user and application requirements. Although more expensive, you can also consider higher density switches as you should not design the network beyond functional requirements. Consider this increase when you reach rack capacity or if you need additional network switches. You can also use QoS for mixed workloads to prevent low-priority, high-bandwidth applications such as backup services, video conferencing, or file sharing, from blocking bandwidth that is needed for the continued operation of other workloads. In this architecture type, OpenStack integrates with Hadoop to manage the Hadoop cluster with Ceph as the storage backend. Network-Focused Architecture Types, 4.5.2. These services are configured for high availability on at least three controller nodes. If you select a centralized storage array, determine how to connect the hypervisors to the storage array. However, cells provide the required scale while exposing a single public API endpoint to users. This architecture type covers 80% of potential use cases, including: This architecture type is not recommended for cloud domains that require increased security. To ensure that the OpenStack infrastructure components are highly available, nodes use the Pacemaker add-on for Red Hat Enterprise Linux together with HAProxy. On a typical 1U server with dual-socket hex-core Intel CPUs with Hyperthreading, and assuming 2:1 CPU over-commit ratio, this architecture requires eight Compute nodes. All OpenStack deployments depend on network communication to function properly because of their service-based nature. Availability. When a user uploads and stores content, that content moves southbound into the OpenStack environment. Assess your average workload, and if need be, increase the number of instances that can run in the compute environment by adjusting the over-commit ratio. Optionally, the controller node runs portions of the Block Storage, Object Big data often uses partial replicas of the data to maintain integrity over large distributed clouds. Active archive, backups and hierarchical storage management, General content storage and synchronization such as a private DropBox service, Data analytics with parallel file systems, Unstructured data store for services such as social media backend storage, Operating system and application image store. Host density. This design includes the following components and workflows: A web service architecture can consist of many options and optional components. See all Clouds used for the management and collection of big data create significant demand on network resources. These permutations of perspectives drive a paucity of aligned user stories to share with the OpenStack and StarlingX communities. Firewall, switches, and hardware load balancers for the public-facing network connections. Other factors that affect content deliver and performance include network throughput of backend systems, resource locations, WAN architecture, and cache methodology. Network configuration affects latency, bandwidth, and distribution of instances. 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. You can create a storage pool to provide block devices with OpenStack Block Storage for instances and object interfaces. OpenStack 101 with Joshua McKenty from Piston Cloud Computing. Use the Telemetry service to perform metering for the purposes of adjusting project quotas. It explains core concepts, cloud architecture design requirements, and the design criteria of key components and services in an OpenStack cloud. This example architecture differs from a minimal production architecture as In the database example, a portion of the SSD pool can act as a block device to the database server. You can deploy more than one compute node. OpenStack Data Processing (sahara) integrates with Hadoop to manage the Hadoop cluster inside the cloud. The current environment does not have the flexibility to align with the company goal of running an open-source API environment. Choose one of the following virtual networking options. Define a reference architecture for edge and far edge deployments including OpenStack services and other open source components as building blocks. This architecture type uses a cloud backup application, where incoming data to the cloud traffic is higher than the outgoing data. Production environments should implement Erasure coded pools are recommended to maximize the amount of usable space. supports all types of cloud environments. 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. You can edit this Block Diagram using Creately diagramming tool and include in your report/presentation/website. Section 4.4.3, “High-Performance Database Architecture”. OpenStack Administrator Guides for Pike. This slideshare explains the architecture of OpenStack. • OpenStack Architecture An OpenStack® based cloud is now a common need by many organizations and Dell Technologies with Red Hat have worked together to build a jointly engineered and validated architecture that details software, hardware, and integration points of all solution components. 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. In order to provide high performance or large amounts of storage space, you might need to attach the storage to each hypervisor or serve it from a central storage device. The routing and switching architecture should accommodate workdloads that require network-level redundancy. Users are sensitive to latency and jitter fluctuations and can detect them at very low levels. Prior to this announcement, IBM had actively invested in integrating its products with OpenStack and made significant contributions to the OpenStack community, helping the software meet enterprise and cloud s… The cloud storage model stores data in logical pools on physical storage devices. Short-lived workloads can include continuous integration and continuous deployment (CI-CD) jobs, which create large numbers of compute instances simultaneously to perform a set of compute-intensive tasks. "Edge" is a term with varying definitions depending on the particular problem a deployer is attempting to solve. implementation, massive scalability, and a rich set of features. with layer-3 (routing) services that enable Run a load balancer in OpenStack as an instance or externally as a service. Consider using the following external network components: Although OpenStack Networking provides a tunneling feature, it is restricted to networking-managed regions. A compute-focused OpenStack cloud is extremely demanding on processor and memory resources. Monitoring of storage resources, such as available storage, memory, and CPU. Attribution 3.0 License. A shared file system or object store maintains initial data sets and serves as the destination for saving the computational results. 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. For example, you can replace the CPU with a CPU with more cores, or increase the RAM of the server. These application types are sensitive to network jitter and latency. Each node requires a minimum of one This can also include Before reading this book, we recommend: Monitoring and reporting for other OpenStack services. The Red Hat OpenStack Platform director is a toolset for installing and managing a complete OpenStack environment. You need more hosts to support the anticipated scale, especially if the design uses dual-socket hardware designs. For information about monitoring software, see Section 3.9, “Additional Software”. The Compute service also runs on each compute node. Because this workload includes an externally-facing service and an internally-replicating application, it requires north-south and east-west traffic considerations. specific guides per version: The example architecture requires at least two nodes (hosts) to launch a basic OpenStack Object Storage to serve static objects, such as images. Except where otherwise noted, this document is licensed under The decision to enable HTT on a CPU depends on the use case. 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. Use this service to monitor instance usage and adjust project quotas. 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. virtual networks to physical networks using NAT. Object Storage service uses for storing accounts, containers, and OpenStack Networking Guide for Rocky, OpenStack offers both Block Storage (cinder) and Object Storage (swift). Manages templates for instances and block storage volume. network instead of a dedicated network. 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. hello, i have been watching videos and reading documents about openstack cloud for more than 2 months, and im willing to test my knowledge by creating my own private cloud. Use a load balancer to serve the VIP and also connect to the tenant overlay network with external methods or private addresses. You can also use HAProxy. It is also used to manage the high-performance bare metal configurations.It is coded in Python and has utilized many pre-defined libraries to deliver robust functioning. The compute node also 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. The architecture includes the following components: Compute management and scheduling services that run on the controller. All architecture examples in this guide assume that you deploy OpenStack Platform on Red Hat Enterprise Linux 7.2 with the KVM hypervisor. North-south traffic consists of data that moves in and out of the cloud. i already have two physical servers. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. The OpenStack user can create virtual networks without the knowledge OpenStack is the open source cloud platform that enables Infrastructure as a Service (IaaS). This service runs on the controller and offers a small set of images. Consider the following factors when you design your storage hardware: In addition to basic network considerations described in Chapter 2, Networking In-Depth, consider the following factors: Section 4.4.1, “Storage-Focused Architecture Types”, Section 4.4.4, “Storage-Focused Architecture Considerations”.
