Cloud applications run in a remote data-center where you do not have full control of the infrastructure or, in some cases, the operating system. The AWS Well-Architected Framework helps enterprise architects build more secure, high-performing, resilient, and efficient cloud-based infrastructure for their applications. Pillar #1 of the AWS Well-Architected Framework: Operational Excellence January 23, 2019 / Vikram Nallamala / No Comments / Amazon Web Services Every software system is built to serve a specific purpose and to achieve clear objectives for a business. Today's users expect an application to be available 24/7 without ever going offline. The cloud is designed to be essentially limitless, so it is the responsibility of AWS to satisfy the requirement for sufficient networking and compute capacity, while you are free to change resource size and allocation, such as the size of storage devices, on demand. Monitoring ensures you are aware of any deviance from expected performance. What Is, Really, AWS Well-Architected Framework? In this post, we shall discuss the five pillars of AWS well-architected framework. When you are designing a cloud solution, focus on generating incremental value early. There are five design principles for cost optimization in the cloud: As with the other pillars, there are trade-offs to consider. Operational Excellence. Use the pay-as-you-go strategy for your architecture, and invest in scaling out, rather than delivering a large investment first version. The scope can be a subscription, a resource group, or a single resource. It provides guidance to help you apply best practices in the design, delivery, and maintenance of AWS environments. It provides guidance to help you apply best practices in the design, delivery, and maintenance of AWS workloads. It provides guidance to help you apply best practices in the design, delivery, and maintenance of AWS workloads. For example: That said, you still need to build resiliency into your application. Spreading VMs across fault domains limits the impact of physical hardware failures, network outages, or power interruptions. This allows you to focus on the other aspects of design, such as functional requirements. The AWS Cloud also provides greater access to security data and an automated approach to responding to security events. At that point, any further scaling must be horizontal. Managed PaaS services often have horizontal scaling and autoscaling built in. Annotated documentation 3. Learn more about the AWS Well-Architected Framework by taking our self-paced training that provides pillar-specific design principles and examples of AWS Well-Architected best practices. Use the cost calculators to estimate the initial cost and operational costs. The AWS Well-Architected Framework is based on five pillars — operational excel-lence, security, reliability, performance efficiency, and cost optimization. It’s important to design operations to support evolution over time in response to change and to incorporate lessons learned through their performance. The framework consists of five pillars of architecture excellence: Cost Optimization, Operational Excellence, Performance Efficiency, Reliability, and Security. Azure Storage, SQL Database, and Cosmos DB all provide built-in data replication, both within a region and across regions. Deployments must be reliable and predictable. When designing an application to be resilient, you must understand your availability requirements. It provides guidance to help you apply best practices in the design, delivery, and maintenance of AWS environments. Click here to return to Amazon Web Services homepage, Scale horizontally to increase aggregate workload availability, Stop spending money on undifferentiated heavy lifting. Learn more about the AWS Well-Architected Partner Program and how your organization can help AWS customers establish good architectural habits and eliminate risk. Finally, establish policies, budgets, and controls that set cost limits for your solution. The training is free, and takes approximately 90 minutes to complete. We believe that having well-architected workload greatly increases the likelihood of business success. How much should you invest in making the application highly available? If the foundation is not solid, structural problems can undermine the integrity and function of the building. The pillars of the AWS Well-Architected Framework Name Description Operational Excellence The ability to support development and run workloads There are five design principles for operational excellence in the cloud: Operations teams need to understand their business and customer needs so they can support business outcomes. Refine operations procedures frequently 5. Keep your eyes peeled for Part 2, where we’ll be deep diving into the Operational Excellence pillar. Having the right monitoring and diagnostics is also important, both to detect failures when they happen, and to find the root causes. Protecting applications and data from threats. Make frequent, small, reversible changes 4. Resiliency strategies can be applied at all levels of the architecture. You can find more details—including definitions, FAQs, and resources—in each pillar’s whitepaper we link to below. The Operational Excellence pillar includes the ability to support development and run workloads effectively, gain insight into their operations, and to continuously improve supporting processes and procedures to deliver business value. Security. There are five design principles for performance efficiency in the cloud: Take a data-driven approach to building a high-performance architecture. Collection and storage. The AWS Well-Architected Framework is based on five pillars: operational excellence, security, reliability, performance efficiency, and cost optimization. Monitoring and diagnostics are crucial. Table 1. For example, do you want to optimize for speed to market or for cost? Azure managed disks are automatically placed in different storage scale units to limit the effects of hardware failures. Use Azure role-based access control (Azure RBAC) to grant users within your organization the correct permissions to Azure resources. Managing costs to maximize the value delivered. For example, you must have sufficient network bandwidth to your data center. Equally important, you must be able to quickly roll back or roll forward if an update has problems. These are the disciplines we group in the operational excellence pillar: In simple words, operational excellence refers to the enhanced ability to run … © 2020, Amazon Web Services, Inc. or its affiliates. If an instance goes down, the application keeps running. Using telemetry data to spot trends or alert the operations team. Ops also collects metrics that are used to measure the achievement of desired business outcomes. Welcome to the Well-Architected Framework, the Operational Excellence Pillar. The WAF Operational Excellence Pillar The OPS and the Security pillar (SEC) form the core of the AWS Well-Architected framework. A reliable workload is one that is both resilient and available. Operational Excellence This pillar is a combination of processes, continuous improvement, and monitoring system that delivers business value and … You’ll want to control who can do what. Monitoring and diagnostics give insight into the system, so that you know when and where failures occur. Use the Performance efficiency checklist to review your design from a scalability standpoint. With AWS, most of these foundational requirements are already incorporated or may be addressed as needed. Resolving one bottleneck may reveal other bottlenecks elsewhere. Did this page help you? Scaling out can be triggered automatically, either on a schedule or in response to changes in load. In addition, you want to be able to identify security incidents, protect your systems and services, and maintain the confidentiality and integrity of data through data protection. Always conduct performance and load testing to find these potential bottlenecks. We recently released an updated version of the Operational Excellence pillar of the AWS Well-Architected Framework, which includes expanded guidance on operating model, and organizational culture, as well as some other refinements. This course takes an in-depth look at the cost optimization pillar. Operational Excellence To achieve well-architected architecture the main pillars reliability, performance efficiency, security and cost optimization must be in place. Just adding more instances doesn't mean an application will scale, however. This pillar is a combination of processes, continuous improvement and monitoring system that delivers business value and continuously improve supporting processes and procedures. Well-Architected workloads use multiple solutions and enable different features to improve performance. Read honest and … Instrumentation. For more information, see our Identity Management reference architectures. Here are some broad security areas to consider. The AWS Well-Architected Framework helps architects build secure, high-performing, resilient, and efficient infrastructures for their applications through five pillars. Everything continues to change—your business context, business priorities, customer needs, etc. Before architecting any system, foundational requirements that influence reliability should be in place. Audit all changes to infrastructure. Operational excellence refers to ensuring that there is full visibility into how the application is running, and ensuring the best experience for the users. Effort was spent trying to prevent the system from failing. What’s New in the Well-Architected Operational Excellence Pillar (09 July 2020)?
