All of us as an individual or in different organizations experience competition. Hence staying updated with the market needs, identifying and understanding what is relevant and what is redundant becomes a must, and critical factor of TIME becomes an integral constituent.
What if there was a way business could focus on their business goals and outsource their maintenance and monitoring tasks somewhere else. Would that help save time and meet the market needs with more efficiency? Migrating to cloud lets you do exactly the same.
In simple words Migration means — ‘Moving your data from an on-premise data center to Cloud is called Migration’ and you have so many cloud provider to choose for this (Google, Microsoft, Oracle ,AWS, many more..).
What are the important consideration points before one choose to migrate applications to cloud. Giving below few of those pointers with focus on migrating to AWS as your cloud partner
- Migration needs
- Phase of AWS Migration
- Migration Strategies
- AWS migration benefits
Migration Needs
Handling situations like security, scaling up or down, etc. pose numerous challenges for traditional deployment strategies . Let’s look at a few scenarios where AWS Migration could be a better resort.
- Product has started receiving a high volume of traffic overnight
- Customer want fast application implementation and deployment
- Huge Database and it’s difficult to mange it
- Handling Failure scenario or providing business continuity during deployment is challenge
If you Migrate to Cloud then the problems mentioned above will get handled automatically.
Phase of AWS Migration
Sharing below, phases of migration which are mostly valid for different business application migration needs. I am not ruling out more items to add to this list
A. Discovery phase to identify which apps can move to cloud
B. Choosing the method of Migration (AWS Direct Connect/ AWS Snowball / AWS Gateway usage)
C. Building POC for Movement , in this we will test different AWS services usage and their benefits to your business use case and demo to important stakeholders
D. Application Migration to cloud once POC gives intended advantages or benefits
E. Maintaining your cloud operation with help from AWS to help your business running smoothly
Application Migration Strategies
Below migration strategies which are also commonly called 6’R’s from Amazon can be used
- Rehost:- You have your application ready and working then you can simply Rehost it on AWS. We also know this with name “Lift and Shift”. You lift your services and applications from your hosting environment and shift them to cloud.
- Replatform:- You have an outdated version of your application running on your hosting environment so you have to modify your application and then Rehost it. Replatform is a modification of “Lift and Shift”. It involves optimizing the cloud architecture to achieve the benefits without changing the core of the application.
- Repurchase:- There would be certain applications that won’t be compatible with the new architecture. AWS Marketplace provides a wide range of services with a “Pay as you Use” model which can be used here.
- Refactor:- You want to add new features/scale up existing business model and performance that are difficult to match with existing environment. Improving business by moving to a service-oriented architecture (SOA)/ Microservice Architecture (MSA) will benefit your business in the longer run.
- Retire:- After AWS Migration you can differentiate between useful and redundant resources. Using this identification, you cut off all the resources that are no longer useful to the business and build strategy around new resources. With lesser things to worry about, now you can focus on maintaining the resources used by the new business model.
- Retain:- Build a strategy to retain those applications, which according to your business model are yet not ready to be migrated to the cloud or the applications that were upgraded recently.
Based on above strategies we can decide part or whole movement to cloud for your enterprise application.
Benefit of moving to AWS Cloud
AWS migration offers many limitless benefits , lets look ate key one’s
- Centralized Infrastructure Management with both Managed services and Customized services offered by AWS
- Satisfying your High Availability (taking care of your DR needs)and Scalability needs
- Providing Elasticity to your product
- Cost Management for your infrastructure by using varied AWS tools towards that side
