Businesses that are migrating to Azure today are doing a basic ‘Lift and Shift’ migration. Lift and Shift is a process of taking what they have On-Prem and then getting the equivalent into the cloud. Experts believe that this is too simplistic and businesses could be missing out a major share of capabilities that Azure offers.
Alternatives to Lift and Shift Migration
While planning a migration, it’s important you get your migration goals straight before hand. Understand what you want to do with your apps instead of just running another instance of a VM? You can either containerize it have an entire different delivery system.
So the idea here is to tear down your processes and services and start applying new technologies to them — technologies such as serverless computing, containerization, or auto-scaling.
Serverless computing is a method of providing backend services on an as-used basis. A Serverless architecture allows users to write and deploy code without the hassle of worrying about the underlying infrastructure. A company that gets backend services from a serverless vendor is charged based on their computation and do not have to reserve and pay for a fixed amount of bandwidth or number of servers, as the service is auto-scaling. Note that although called serverless, physical servers are still used but developers do not need to be aware of them. The advantages of serverless is as follows:
- Lower costs – Serverless computing is generally very cost-effective, as traditional cloud providers of backend services (server allocation) often result in the user paying for unused space or idle CPU time.
- Simplified scalability – Developers using serverless architecture don’t have to worry about policies to scale up their code. The serverless vendor handles all of the scaling on demand.
- Simplified backend code – With FaaS, developers can create simple functions that independently perform a single purpose, like making an API call.
- Quicker turnaround – Serverless architecture can significantly cut time to market. Instead of needing a complicated deploy process to roll out bug fixes and new features, developers can add and modify code on a piecemeal basis.
Containerization is the process of packaging an application along with its required libraries, frameworks, and configuration files together so that it can be run in various computing environments efficiently. In simpler terms, containerization is the encapsulation of an application and its required environment. Containers:
- Are much more lightweight than a VM
- Reside at host OS rather guest OS level
- Many can run on top of the operating system kernel
- Can start much faster and use far less memory than booting to an entire OS
- Are the fundamental building blocks for microservice architecture where all apps are developed as suites of independent services
When you have resources that need to be scaled up and down, autoscaling can save the exact purpose. For instance, your apps may perhaps be on high demand during business hours and less used during the night time. At those times, autoscaling lets you use as much as needed and pay as much as needed.
Instead of just lifting and shifting during your on-premise to Azure migration, consider what using it as a platform-as-a-service means. In this scenario, the platform is responsible managing itself. And the incremental cost is just nil.
Its important that you automate and modernize. Don’t just lift and shift.
Steps of Migration
Don’t just jump into the cloud. Plan your Azure migration process.
1. Assess what you have
Assess your infrastructure and measure what your ROI might be in a move to the Cloud. Check infrastructure and software and evaluate the costs such as licensing costs, Power costs, Space utilization costs, Staffing costs etc associated with it.
You need to categorize everything and determine where your biggest savings will come from. Perhaps the server space you now have is needed for new employees for your growing company. What will you save by not needing to construct a new space? Or perhaps you’ll be able to eliminate some IT staff who currently do all the patching, backing up, and server maintenance. Evaluate your options, measure the possibilities to cost minimization.
2. Where will you find benefits?
Think about what’s holding you back now. How can you get past that. Do you want benefits to come out of performance, cost, or reduced risk? Look at it in kind of a matrix, see what scores the highest in benefits and focus your energies on that.
3. Determine your ideal time
Determine the best time to start your migration. For example, instead of laying out $50,000 to $100,000 in the long list of renewalscoming up, defer some of it. Take some of the low-hanging fruit — think your Exchange server and Office software — and start your migration there.
4. The Size of your migration goals
You might have had different sizes of Migration. For example, a small modernization might just involve supplying a simple application or platform. A medium-size would involve applying for an application or platform, which requires some customer interaction. An extra large modernization could be the migration of a very complex, custom, and multi-tier application.
Once you’ve decided what you’re going to migrate, it’s important that you prepare. You do need some due diligence to understand what needs to be done.
The next step is validation. You need to assess whether your on-premises workloads are ready for migration. If not, make sure they are validated before migrating over — otherwise, you can make some critical mistakes that will be hard to undo.
The benefits of on-premises to Azure migration you are missing out while choosing Lift and Shift
Let’s look at some concrete benefits that could be yours when you doing an on-premises to Azure migration instead of a lift and shift.
Centralization can make you sit at the control panel and provision, move, do whatever you want across the infrastructure that could be anywhere in the world. And, you can do it from anywhere.
Reduced labor cost
If you’re like many companies, you’ve got one IT guy focusing on SANS and storage, and another on networking, while another focuses on yet another part. It’s very verticalized and you’re very dependent on each of those people. When you migrate to the cloud, much of those functions can get consolidated down and one person can play that role.
Pay for what you use
You can spin up an instance, test it, find a few issues, spin it down, and fix it — for minimal cost since you only pay for what you use. And the fixing part is on your time and your equipment. Then you can spin up again, test again, and spin down again. If you need more capability on, say a Black Friday, simply scale up, and when the day’s over, scale it back down. Microsoft says that you should be able to see 30% cost reduction.
Be quick or get left behind
One of Azure’s exceptional benefits is speed — speed of deployment, speed of operation, and speed of scalability.
