Like the name suggests, application migration is the process of moving an application from one environment to another. It can be used to move an application from on-premise to the cloud or from one cloud provider to another. While it can offer many benefits, application migration can also be a little tricky. According to a recent survey 72% migrants had to shift their applications back to on-prem because of the issues faced in cloud migration. 21% of these respondents have confirmed to choosing the wrong CSP (Cloud Service provider) for their business.
Application migration service uses a 3-step outlook when it comes to disaster recovery: Prevention, anticipation, and mitigation. However, once a disaster strikes there are a few key elements such as communication (internal and external), recovery timeline, data backups, testing, and optimization.
What is Application Migration Service?
AMS is a cloud-based service that helps you move your on-premise workloads to (AWS). With application migration, you can replicate your application environment to AWS and efficiently update it whenever your on-premises environment changes. AMS provides an end-to-end solution for disaster recovery, backup, and migrations.
AMS is particularly well-suited for replicating disaster recovery (DR) environments in AWS. Due to the seamless synchronization of the application environment, you can ensure its availability when you need it, without worrying about maintenance. As mentioned earlier, AMS automates the process of replicating and updating your DR environment for a fully up-to-date migration process.
Application migration can be used to protect your applications/data and can help you recover from a disaster. By utilizing these services, you can maintain your business operations during times of emergency or disruption by avoiding long down times. The AMS allows you to move your applications onto a new server, hosted at Microsoft’s data center with all your existing data and applications on it. This enables maintaining much of your current infrastructure while allowing a quick transition into the new environment.
How to migrate an application to AMS?
If you’re looking to migrate an application to AMS, there are a few things you’ll need to keep in mind. First, you’ll need to identify which parts of the application can be migrated and which parts need to be rewritten. Once that part is taken care of, you need to plan the migration by each step. Finally, you’ll need to execute the migration plan and test the application in the new environment to ensure it works as intended.
What are the risks of AMS?
The most notable risk associated with application migration is data loss. While migrating applications to AMS, there is a 50% potential for data to be lost in transit. Additionally, some data may be corrupted (23% risk of application stability) if there are issues with the migration process itself. Some other issues with the process are lack of storage, and inefficient data recovery plan documentation. While these risks are relatively low, you must be aware of them before using AMS to have a robust recovery plan along with data migration testing to reduce the risks.
What recovery options does AMS provide?
AWS AMS simplifies, and automates the process. AMS can migrate your application data, dependencies, and configure your application for optimal performance on AWS.
If you experience problems with your migrated application on AWS, the first step is to check the Amazon CloudWatch console for error messages. CloudWatch is a monitoring service providing visibility into your AWS resources and applications. If there are any visible errors in the console, you can troubleshoot them using the information in the Amazon CloudWatch logs. After checking the console, you can contact AWS Support if the problems persist. AWS Support is a one-stop-shop for all your technical questions about AWS products and services. Their team of technical experts can help troubleshoot your problems to get your application up and running on AWS.
AMS offers a disaster recovery service with access to your data and applications when you need them the most. The Disaster & Recovery team will evaluate your needs and challenges to help you find solutions that fit with an RTO (Recovery Time Objective) of approximately 1 hour depending on the number of instances and orchestration.
Moreover, you can also consider a few things to cut your data losses. Understanding your data and making a flow from least to most crucial data to migrate is helpful. Access control and encryption of data during the shift are some other ways to make your migration journey more efficient. The ability to quickly restore your business is crucial, which is why AMS offers an extensive selection of options for restoring your systems and data from physical servers to virtual machines and storage.
