Cloud migration is high on the priority list for enterprises and small businesses alike. There are however several variables that affect the outcome and each organization’s migration journey is likely to be different. There are several dos and don’ts when it comes to planning the cloud migration process, and these vary with every business case. However there a few standard practices outlined by experts and cloud service providers that are good to follow to ensure a positive and least disruptive outcome.
Amazon Web Services (AWS) recommends a comprehensive assessment be undertaken at the start of the cloud migration journey. You should use this opportunity to identify the desired business outcomes. AWS provides a host of resources like Cloud Adoption Readiness Tool, Migration Evaluator, and others to help you assess strengths and opportunities and cost projections.
Educate your team
After reaching out to key stakeholders in your organization to get them on board with cloud migration, it is necessary to train your team in the fundamentals of cloud computing. Microsoft’s Azure, for example, offers free training and resources and certification that teams can take advantage of to be able to fully benefit from cloud capabilities.
Choose your cloud integration options
There are several migration strategies, but essentially, on-premise applications can be migrated either via shallow or deep cloud integration. The shallow cloud integration approach (lift-and-shift) is the fastest to implement as it requires minimal or no changes to the application. Deep cloud integration requires a certain level of modifications to be performed on the application during the migration process to capitalize on critical cloud capabilities like dynamic load balancing, auto-scaling or serverless computing capabilities.
Set cloud KPIs
You may have already defined your Key Performance Indicators (KPIs) for your applications on-premise, but these may need to be revisited once on the cloud. Additional cloud migration KPIs may need to be defined so you can measure the success of the migration process. Some of these KPIs could be for example, with regards to the user experience as in page loading time, response time and session time, or in infrastructure with CPU usage or memory storage.
Microsoft Azure recommends beginning your cloud migration with low complexity workloads as a pilot. These workloads can be assessed using Azure Migrate. The pilot can be performed with the migration of databases to the Azure cloud using the Azure Database Migration Service.
Have a back-up
It is good practice to keep back-ups before starting the cloud migration process in case of accidental deletions or road bumps. It is also essential to track recovery time objectives and recovery point objectives for individual applications.
Mobilize and modernize
This is the AWS strategy which recommends moving to the cloud and then re-architecting in AWS. There are a number of AWS resources like CloudEndure which enables quick rehosting of machines from multiple source platforms to AWS without disruption. The AWS Migration Hub provides progress updates as well as enables businesses to easily identify and troubleshoot any migration issues.
