If you are from a business, you must get to hear this term “move to the cloud” very often from every vendor or even from your own people if you have contacted them for some sort of solutions for cost optimization or to avail higher performance & availability or resiliency.
After having the same response from multiple experts, if you still don’t feel the confidence to move to cloud, it could be because you may not have updated yourself of the cloud benefits, or you may be fret of a lot of hard work and tough decisions you may have to make during your adoption and migration journey to cloud.
What Is Cloud Migration?
A cloud migration is the process of moving some or all of its data center capabilities into the cloud, usually to run on the cloud-based infrastructure provided by a cloud service provider such as AWS, Google Cloud, or Azure.
As more and more companies have already transitioned to the cloud, cloud migrations are increasingly taking place within the cloud, as companies migrate between different cloud providers (known as cloud-to-cloud migration).
Types Of Cloud Migration Strategies
Migrating to the cloud could be a smart investment for your business. But like many companies, you might be wondering where to start. Let’s hold off on planning your strategy for a moment and first go over your options.
Cloud migration strategy is a smart investment for a business, enabling them to boost performance and security of business applications. Now, if you are thinking about where to start the journey, let us show and discuss with you the path ahead. Cloud adoption begins with 6 R that we are discussing in detail below:
1. Rehosting (Or Lift-And-Shift)
It involves using infrastructure-as-a-service (IaaS). You simply redeploy your existing data and applications on the cloud server. It is an act of picking up the business application and deploying it over the new hosting environment of the cloud. You don’t need to modify the app’s code or architecture to use cloud in the method. Nonetheless, rehosting is considered by companies new to cloud computing and desire to leverage the speed of deployment in less time or money.
2. Re-Platforming (Lift, Tinker And Shift)
Going with a re-platforming cloud strategy allows you to tweak and optimize applications so that you can better use cloud-based tools. In this case, a platform-as-a-service (PaaS) model is employed. However, the core architecture of the applications remains unchanged. It is a good approach for companies that don’t want to expand and to build trust over cloud.
3. Refactoring (Re-Architecting)
If you want to take advantage of highly advanced cloud features, refactoring is the best fit for you. Refactoring is a process of rebuilding your applications from scratch to leverage cloud-native capabilities that you couldn’t otherwise like auto-scaling or serverless computing. A potential drawback, however, is that refactoring invites vendor lock-in because you are rebuilding on a native cloud infrastructure. Moreover, building cloud-native applications is a time-consuming and expensive route; it is the most future-proof for companies for future requirements.
4. Re-Purchasing (Drop & Shop)
Re-purchasing is the best solution for companies struggling with highly customized legacy landscapes and facing challenges for managing multiple services or apps. With a re-purchasing cloud migration strategy, you are required to completely replace your existing applications with a cloud-native, saas-based platform such as a homegrown CRM with salesforce. The challenge is that your people may not be familiar with a new platform, and due to this, you may have to set up training for your team. But it saves your development cost.
If there are applications in your system that are no longer useful, you can decommission or archive unneeded parts of it, and that thing comes in retirement. Putting them off results into savings that might serve to boost your business case for application migration when you are ready to make a move.
Revisiting is such a cloud migration approach that helps you do it skillfully without affecting business operations. Revising builds upon the previous strategies, requiring more significant changes to the architecture and code of the systems being moved to the cloud. This is done to enable applications to take full advantage of the services available in the cloud, which may require introducing major code changes.
This strategy requires foreplanning and advanced knowledge.
What Are The Benefits Of Cloud Migration?
Companies are adapting and moving to cloud for several reasons, but generally when facing the challenge of growing their IT infrastructure with the need to keep the budget low and ensuring optimum security requirements. Whereas migrating data and applications to the cloud provide ample benefits. A few of among them are as follows:
The market is constantly changing so does the user interest. You can’t predict when and in what ways your business will experience fluctuations in traffic, but the cloud can predict. Cloud infrastructure here offers you the advantage to scale up or down your resources and meet the demand of any size in no time.
When your business starts growing, the need for databases, analytics, and other snowballing workloads also increases simultaneously. In that situation, cloud allows you to expand within existing infrastructure, and your applications get room to grow without affecting performance.
Cloud is the answer to the rapid changes in technology resources. Cloud does this by drastically reducing the time it takes to procure new inventory and storage.
CSPs easily handle the complexities of the infrastructure that help you focus on productivity. Moreover, remote accessibility of most cloud solutions allows your team to focus on growing the business.
You get better security with cloud migration than on-premise data centers. All the top cloud providers focus on enabling security and thus provide built-in features, including periodic updates, security analytics, and cross-enterprise visibility.
Cost-optimization comes under every company’s mission, and cloud also solves the issue easily. For cloud services, cloud providers are offering a pay-as-you-use model. Meaning you only pay for the resources you have used. No more investment is required to update, maintain, train or create space for physical servers.
The best part? cloud-based applications offer enhanced performance and are quick to innovate with growing customer’s requirements.
How Do I Migrate To The Cloud?
One-size-fits-all doesn’t work when it comes to migrating data and applications to the cloud. Your cloud migration strategy must be designed and defined based on your business model, size and complexity of the current environment, as well as migration goals. Gartner recently reported that as much as 81% of the companies that are in the public cloud are using more than one service provider. There are many reasons why cloud migration strategy would call for these kinds of multi cloud and hybrid approaches. Your CSP also helps you understand the ins and outs of your current environment and help you design a roadmap that shows how, when and how much business needs cloud migration. Apart from that, the vital thing is to analyze the below factors as they widely influence your cloud migration budget and productivity:
- Whether you want to go with AWS, Azure, GCP, or others.
- Whether your need is single cloud, hybrid cloud or multiple cloud
- Whether your cloud computing model should be SaaS, PaaS, or IaaS.
Once you are sure with your cloud requirements and clear with your cloud migration strategy, you can relax as your cloud service provider will do the heavy lifting for you, and you can focus on your business growth.
Cloud migration could be a nightmare if you don’t move ahead with a strategy. The solution directly addresses the people, process, technology, and financial considerations of the company throughout the migration journey to ensure your project achieves the desired business outcomes.
