In the high performance analytics example, the inline SSD cache layer accelerates the REST interface. You must also consider fault domains and power density. In the last article ,we have seen the history of private cloud softwares and Openstack. 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. Choose one of the following virtual networking options. For information on creating architectures for specific Each node requires a Essentially, it bridges virtual This configuration provides a globally-routable IPv6 address, while consuming IPv4 addresses only as necessary. OpenStack Reference Architecture For 100, 300 and 500 Nodes¶. Similar to VoIP, users of these system notice network performance problems even at low levels. However, the term can also include other types of data storage that are available as a service. If your company has an existing Red Hat account, your organization administrator can grant you access. The example architecture used in this guide is a minimum configuration, Consider using RAID controller cards in compute hosts to improve the performance of the underlying disk sub-system. Optionally, the controller node runs portions of the Block Storage, Object Higher port density allows more rack space for compute or storage components. All OpenStack deployments depend on network communication to function properly because of their service-based nature. Connectivity can affect latency and performance. Cloud-based file storage and sharing service, commonly used in OpenStack deployments. VLAN networks if the layer-2 plug-in is configured accordingly. Automatically deploys and tests new instances. If you plan too aggressively, you might experience unexpected underutilization of the cloud unnecessary operations and maintenance costs. 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. Additionally, a DHCP service provides IP address information to This configuration is recommended for data centers with older infrastructure. In this example, you can expand the architecture further as needed. For more information on production architectures for Rocky, see the various Networking agents, and the Dashboard. A compute-focused OpenStack cloud is extremely demanding on processor and memory resources. The connectivity must satisfy the storage solution requirements. 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”. z/VM's focus is on enabling OpenStack APIs, not providing an end-user GUI. It is designed to These architectures must balance a high volume of east-west traffic with north-south traffic to maximize data delivery efficiency. OpenStack Data Processing (sahara) integrates with Hadoop to manage the Hadoop cluster inside the cloud. If you are a new customer, register now for access to product evaluations and purchasing capabilities. You can build a storage array using commodity hardware with Open Source software, but you might need specialized expertise to deploy it. For example, a switch that provides 48 ports with 10 GbE capacity for each port in a 1U server has higher port density than a switch that provides 24 ports with 10 GbE capacity for each port in a 2U server. 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. Consider enabling HTT to improve the performance of multi-threaded applications. KVM hypervisor. These permutations of perspectives drive a paucity of aligned user stories to share with the OpenStack and StarlingX communities. Backups run every six hours. Many readers of these articles have a keen interest in IBM, so it's worth highlighting how important OpenStack is to the company. Increase security using methods such as firewalls, encryption, and In addition to basic design considerations described in Chapter 3, Design and compute node design considerations described in Section 3.2, “Compute Resources”, the following items should be considered for a compute-intensive architecture. 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. This architecture type provides SSL-offload functionality and connects to tenant networks to reduce address consumption and scale the Web application horizontally. The configuration depends on your selected network hardware, on the selected hardware performance, and on your networking model. In addition, it requires manual replication of some configuration elements, such as flavors, across cells. You can address the higher host count with a quad-socket platform. Some workloads require a larger MTU due to the transfer of large blocks of data. If one site becomes unavailable, additional sites can serve the increased load until the original site returns to service. Parallel file systems can provide high-performance data processing and are recommended for large scale performance-focused systems. High-Performance Database Architecture, 4.4.4. You can deploy a general high availability cloud if you are unsure of specific technical or environmental needs. The controller node requires a minimum of two network interfaces. North-south traffic consists of data that moves in and out of the cloud. Openstack.org is powered by This service requires two nodes. High-performance storage system that assumes increased database IO requirements and utilizes a solid-state drive (SSD) to process data. Architecture Design Guide. Latency. 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. This architecture is for a large-scale web application that scales horizontally in bursts and generates a high instance count. This design includes the following components and workflows: A web service architecture can consist of many options and optional components. to automate deployment and management of the production environment. Deployments can also be based on deployed infrastructure. This guide introduces the OpenStack cloud components and provides design guidelines and architecture examples to help you design your own OpenStack cloud.
