Getting going – when I started as a customer building on AWS, the team and I went through multiple revisions of creating our landing zone and multi account strategy. Cloud setup and governance can be complex and time consuming, slowing down the very innovation you’re trying to speed up. Customers today no longer have to spend time doing this. This week we launched AWS Control Tower Data Sovereignty – organizations that operate in highly regulated industries or the public sector often need to control where their customer data is stored and processed—a concept known as data residency. Customer data is the personal data uploaded to AWS services under their AWS accounts. With AWS Control Tower, customers can now implement data residency preventative and detective controls in minutes with a set of purpose-built guardrails to help keep their customer data in the AWS Region or Regions they specify, helping you build and use in a highly regulated environment even faster. Next, we come to Refactoring – looking after the hundreds of peop...

“How emigration is actually lived — well, this depends on many factors: education, economic station, language, where one lands, and what support network is in place at the site of arrival.” -DanielAlarcón This post outlines 6 different migration strategies we see customers implement to migrate applications to the cloud. These strategies build upon the 5 R’s that Gartner Formulating a Migration Strategy Enterprises typically begin to contemplate how to migrate an application during the second phase of the “ Using this knowledge, organizations can outline a plan (which should be considered subject to change as they progress through their migration and learn) on how they’ll approach migrating each of the applications in their portfolio and in what order. The complexity of migrating existing applications varies, depending on the architecture and existing licensing arrangements. If I think about the universe of applications to migrate on a spectrum of complexity, I’d put a virtualized, service-oriented architecture on the low-complexity end of the spectrum, and a monolithic mainframe at the high-complexity end of the spectrum. I suggest starting with something on the low-complexity end of the spectrum for the obvious reason that it will be easier to complete — which will give you some immediate positive reinforcement or “quick wins” as you learn. 6 Application Migration Strategies: “The 6R’s” The 6 most common application migration strategies we see are: • Rehosting — Otherwise...

The next step is to identify and plan a migration path that's tailored for your workloads. The Understand your digital estate Start by identifying your on-premises infrastructure, applications, and dependencies. This helps you to identify workloads for migration to Azure, and to gather optimized cost projections. The Discovery and assessment tool helps you to identify the workloads you have in use, dependencies between workloads, and workload optimization. Workloads in use Azure Migrate uses a lightweight Azure Migrate appliance to perform agentless discovery of on-premises VMware VMs, Hyper-V VMs, other virtualized servers, and physical servers. Continuous discovery collects server configuration information, and performance meta...

Cloud migration is the process of relocating an organization’s data, applications, and workloads to a cloud infrastructure. Your organization may choose to relocate all of its computing assets to a cloud; however, in most cases, some applications and services still remain on-premise. Migration may involve one or more clouds. Some clouds are Check out our video, "What is Cloud Migration?" for more of an overview: The following are a few of the ways your organization can benefit from migrating data and workloads to the cloud: • Scalability: The cloud removes the physical constraints to scalability and reduces the financial limitations of adding servers and the supporting infrastructure to a data center. • Cost-effectiveness: The cloud lets you pay for only the capacity you use. Instead of adding on-premise capacity to anticipate scalability you may or may not need, with cloud, you pay only for the capacity you need now and scale on demand when you need to. • Security: Clouds typically are secure environments that comply with applicable industry standards and government regulations. They are protected through security solutions and tools, best practices, and policies that cloud providers update as needed on a regular basis and at scale. • Accelerated adoption: Migrating applications to the cloud allows your company to adopt new technologies faster, while also enabling affordable, just-in-time technology adoption in response to business opportunities. In short, enterprises typ...

As your organization prepares for cloud migration, it is vital that your IT team maintains a comprehensive view of all infrastructure components and available options for migrating each workload. The better you understand what you’re working with, the easier project planning and execution becomes. Migrating complex IT systems should be done incrementally. Inventorying your systems and in-use applications is the first step in developing your actionable cloud migration plan. Next, you should identify specific types of cloud migration to be performed with each item. So, what are the cloud migration types? These are the most commonly used approaches: • rehosting • re-platforming • repurchasing • refactoring • retaining • retiring These strategies are commonly referred to as “the 6 R’s of cloud migration”. When deciding which “R” to use, prioritize the mission-critical services for optimization and refactoring and tackle the rest of your workloads with a simple lift-and-shift. It also can be useful to start from some lower risk non-critical workloads as a pilot test to help you refine the migration process as you get to the critical infrastructure components. Let's discuss the operational benefits and business merit of these strategies in detail. Rehost or lift-and-shift model Rehosting is the most straightforward cloud migration path. It means that you lift applications, virtual machines, and server operating systems from the current hosting environment to public cloud infrast...

A cloud migration strategy is defined as a plan that an organization formulates to move all the resources in its infrastructures, such as data, services, and applications, to the cloud. Click here to understand what a cloud migration strategy is, the key factors influencing the cloud migration strategy for enterprises, and the best practices in 2021. Table of Contents • • • A cloud migration strategy is a plan that an organization formulates to move all the resources in its infrastructures, such as data, services, and applications, to the cloud. Cloud adoption rates have been soaring since the early 2000s when companies such as Salesforce and Amazon introduced the cloud concept to the market. The onset of the 2020 COVID-19 pandemic saw enterprises reporting even more cloud usage than before. The reason for this is largely attributed to remote working requirements coupled with the need to continue driving innovation. According to the 2021 Flexera State of Cloud report, 90% of enterprises expect cloud usage to exceed prior plans this year as well. Cloud migration is the process of moving all digital resources to the cloud from either on-premise deployments or from another cloud. Formulating a robust cloud migration strategy is the first step toward migration. As of today, most organizations already have at least one cloud component in their architecture. But according to Flexera’s report, on average, businesses estimate that they waste 30% of their spending on the cloud. In ...
