An updated version of the Operational Excellence pillar of the AWS Well-Architected Framework has just been released, which includes expanded guidance on operating model, and organizational culture, as well as some other refinements. True cloud scale. The ability of a system to adapt to changes in load. You can add more instances if load increases, or remove them during quieter periods. You would then need to consider additional measures, such as optimistic concurrency or data partitioning, to enable more throughput to the database. The framework consists of five pillars of architecture excellence: Cost Optimization, Operational Excellence, Performance Efficiency, Reliability, and Security. If the foundation is not solid, structural problems can undermine the integrity and function of the building. Apply the principles of Build-Measure-Learn, to accelerate your time to market while avoiding capital-intensive solutions. Performance efficiency is the ability of your workload to scale to meet the demands placed on it by users in an efficient manner. How much will potential downtime cost your business? Tactical mitigations can make a big difference. The OPS pillar is a catalyst for the other five pillars because it’s mostly about automation in the development and deployment process. Collection and storage. The framework is based on five pillars: • Operational Excellence • Security • Reliability • Performance Efficiency • Cost Optimization This paper focuses on the security pillar. Running several small VMs can cost less than a single large VM. The Security pillar includes the ability to protect data, systems, and assets to take advantage of cloud technologies to improve your security. It provides guidance to help you apply best practices in the design, delivery, and maintenance of AWS workloads. The AWS Cloud also provides greater access to security data and an automated approach to responding to security events. Always conduct performance and load testing to find these potential bottlenecks. Cost Optimization. The pillars of the AWS Well-Architected Framework Name Description Operational Excellence The ability to support development and run workloads The operational excellence pillar includes the ability to run and monitor systems to deliver business value and to continually improve supporting processes and procedures. Protecting applications and data from threats. Table 1. In a large application, it's not practical to log into VMs to troubleshoot an issue or sift through log files. Make frequent, small, reversible changes 4. Infrastructure should be … Learn vocabulary, terms, and more with flashcards, games, and other study tools. Operational Excellence This pillar is a combination of processes, continuous improvement, and monitoring system that delivers business value and … The Cost Optimization pillar is about optimizing costs, eliminating, unused or sub … The stateful parts of a system, such as databases, are the most common cause of bottlenecks, and require careful design to scale horizontally. Because AWS physically secures the infrastructure that supports our cloud services, as an AWS customer you can focus on using services to accomplish your goals. All rights reserved. But at some point you'll hit a limit, where you can't scale any up any more. Welcome to the Well-Architected Framework, the Operational Excellence Pillar. Gather data on all aspects of the architecture, from the high-level design to the selection and configuration of resource types. Monitoring and diagnostics are crucial. You can find prescriptive guidance on implementation in the Performance Efficiency Pillar whitepaper. We believe that having well-architected workload greatly increases the likelihood of business success. The ability of a system to recover from failures and continue to function. Operational excellence refers to ensuring that there is full visibility into how the application is running, and ensuring the best experience for the users. If you want to integrate an on-premises Active Directory environment with an Azure network, several approaches are possible, depending on your requirements. Azure has many resiliency features already built into the platform. April 2020 The focus of this paper is the operational excellence pillar of the Amazon Web Services (AWS) Well-Architected Framework. The framework provides a set of questions that allows you to review an existing or proposed architecture. Consolidating the data into one place. The AWS Well-Architected Framework was created to help cloud architects build the most secure, high-performing, resilient, and efficient infrastructure for their applications. For example, if you scale a web front end to handle more client requests, that might trigger lock contentions in the database. Equally important, you must be able to quickly roll back or roll forward if an update has problems. But each VM in the pool must be able to handle any client request, so the application must be stateless or store state externally (say, in a distributed cache). Click here to return to Amazon Web Services homepage, Scale horizontally to increase aggregate workload availability, Stop spending money on undifferentiated heavy lifting. In some cases, it’s best to optimize for speed—going to market quickly, shipping new features, or simply meeting a deadline—rather than investing in up-front cost optimization. Using telemetry data to spot trends or alert the operations team. This allows you to focus on the other aspects of design, such as functional requirements. With AWS, most of these foundational requirements are already incorporated or may be addressed as needed. Monitoring and diagnostics are crucial. Learn more about the AWS Well-Architected Partner Program and how your organization can help AWS customers establish good architectural habits and eliminate risk. Spreading VMs across fault domains limits the impact of physical hardware failures, network outages, or power interruptions. To assess your workload using the tenets found in the Microsoft Azure Well-Architected Framework, see the Microsoft Azure Well-Architected Review. In this post, we provide an overview of the Well-Architected Framework’s five pillars and explore design principles and best practices. Ops also collects metrics that are used to measure the achievement of desired business outcomes. Monitoring and diagnostics give insight into the system, so that you know when and where failures occur. In general, the security best practices for application development still apply in the cloud. This pillar is a combination of processes, continuous improvement, and monitoring system that delivers business value and continuously improve supporting processes and procedures. Pillar 1 : Operational Excellence. Some mitigations are more tactical in nature — for example, retrying a remote call after a transient network failure. Security. The Performance Efficiency pillar includes the ability to use computing resources efficiently to meet system requirements, and to maintain that efficiency as demand changes and technologies evolve. Use the cost calculators to estimate the initial cost and operational costs. There are five design principles for performance efficiency in the cloud: Take a data-driven approach to building a high-performance architecture. Just adding more instances doesn't mean an application will scale, however. The Reliability pillar encompasses the ability of a workload to perform its intended function correctly and consistently when it’s expected to. Horizontal scaling can also improve resiliency, by adding redundancy. In an on-premises environment, these requirements can cause long lead times due to dependencies and therefore must be incorporated during initial planning. Today's users expect an application to be available 24/7 without ever going offline. Think about security throughout the entire lifecycle of an application, from design and implementation to deployment and operations. Use Key Vault to safeguard cryptographic keys and secrets. Deployments must be reliable and predictable. Horizontal scaling has significant advantages over vertical scaling: An advantage of vertical scaling is that you can do it without making any changes to the application. It’s important to design operations to support evolution over time in response to change and to incorporate lessons learned through their performance. Security on the cloud is a big concern for everyone on the cloud. Finally, establish policies, budgets, and controls that set cost limits for your solution. The training is free, and takes approximately 90 minutes to complete. Everything continues to change—your business context, business priorities, customer needs, etc. This includes the ability to operate and test the workload through its total lifecycle. Vertical scaling (scaling up) means increasing the capacity of a resource, for example by using a larger VM size. The AWS Well-Architected Framework is based on five pillars: operational excellence, security, reliability, performance efficiency, and cost optimization. The AWS Well-Architected Framework provides architectural best practices across the five pillars for designing and operating reliable, secure, efficient, and cost-effective systems in the cloud. Understanding the AWS Well-Architected Framework pillar: Operational excellence - Hi there, Mark Wilkins checking in. Having the right monitoring and diagnostics is also important, both to detect failures when they happen, and to find the root causes. Applications often depend on external services, which may become temporarily unavailable or throttle high-volume users. Understanding the AWS Well-Architected Framework pillar: Operational excellence - Hi there, Mark Wilkins checking in. In this post, we shall discuss the five pillars of AWS well-architected framework. Generating the raw data, from application logs, web server logs, diagnostics built into the Azure platform, and other sources. The Cost Optimization pillar includes the ability to run systems to deliver business value at the lowest price point. April 2020 The focus of this paper is the operational excellence pillar of the Amazon Web Services (AWS) Well-Architected Framework. Pillar 1 : Operational Excellence The ability to support development and run workloads effectively, gain insight into operations and to continuously improve supporting procedures and processes to deliver business value. All systems must be observable. Amazon Web Services –Operational Excellence AWS Well-Architected Framework Page 1 With PaaS services, there may not even be a dedicated VM to log into. They should be a fast and routine process, so they don't slow down the release of new features or bug fixes. 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. 1 Operational Excellence Pillar AWS Well-Architected Framework To troubleshoot issues and see the overall health. The Framework comprises five pillars: operational excellence, security, reliability, performance efficiency, and cost optimization. Many Azure storage and DB services support data encryption at rest, including Azure Storage, Azure SQL Database, Azure Synapse Analytics, and Cosmos DB. For example, you must have sufficient network bandwidth to your data center. Applications can be designed to run on hundreds or even thousands of nodes, reaching scales that are not possible on a single node. Managed PaaS services often have horizontal scaling and autoscaling built in. For example, do you want to optimize for speed to market or for cost? You can find prescriptive guidance on implementation in the Operational Excellence Pillar whitepaper. This pillar is a combination of processes, continuous improvement and monitoring system that delivers business value and continuously improve supporting processes and procedures. Scaling out may be cheaper than scaling up. Start studying KNOWLEDGE CHECK: WELL-ARCHITECTED PILLAR 1: OPERATIONAL EXCELLENCE. For example: That said, you still need to build resiliency into your application. Anticipate failure 6. The WAF Operational Excellence Pillar The OPS and the Security pillar (SEC) form the core of the AWS Well-Architected framework. But how do ensure that all these are effective throughout the execution of your services and resources. The operational excellence pillar provides an overview of design principles, best practices, and questions. While it's rare for an entire region to experience a disruption, transient problems such as network congestion are more common — so target these first. Horizontal scaling (scaling out) is adding new instances of a resource, such as VMs or database replicas. Effort was spent trying to prevent the system from failing. You can find prescriptive guidance on implementation in the Operational Excellence Pillar whitepaper. Consider using Azure Active Directory (Azure AD) to authenticate and authorize users. It includes making the development and release practices more agile, which allows the business to quickly adjust to changes. Using the appropriate services, resources, and configurations for your workloads is key to cost savings. What’s New in the Well-Architected Operational Excellence Pillar (09 July 2020)? These are the disciplines we group in the operational excellence pillar: When architecting technology solutions on Amazon Web Services (AWS), if you neglect the five pillars of operational excellence, security, reliability, performance efficiency, and cost optimization, it can become challenging to build a system that delivers on your expectations and requirements. Read honest and … It might simply push the bottleneck somewhere else. We believe that having well-architected workloads greatly increases the likelihood of business success. Equally important, you must be able to quickly roll back or roll forward if an update has problems. Cloud applications often use managed services that have access keys. The workload architecture of the distributed system must be designed to prevent and mitigate failures. In cloud computing, a different mindset is required, due to several factors: All of these factors mean that cloud applications must be designed to expect occasional failures and recover from them. Using the Framework in your architecture helps you produce stable and efficient systems, which allows you to focus on functional requirements. The focus of this paper is the operational excellence pillar of the AWS Well-Architected Framework. This pillar covers the operations processes that keep an application running in production. But you still need to build security into your application and into your DevOps processes. There are seven design principles for security in the cloud: Before you architect any workload, you need to put in place practices that influence security. This might lead to over-provisioned and under-optimized deployments. For serverless workloads, AWS provides multiple core components (serverless and non-serverless) that allow you to design robust architectures for your serverless applications. Creating a software system is a lot like constructing a building. You’ll want to control who can do what. Operational Excellence. Well-Architected Framework. The ease of scaling these services is a major advantage of using PaaS services. Visualization and alerts. Costs for cloud environments are kept low through the use of commodity hardware, so occasional hardware failures must be expected.
