Migrating, extending, and managing your database(s) to the cloud can be more complicated than you think. Here are four examples of the challenges you may face.
Protecting your entire IT infrastructure both on-premises and in a hybrid cloud, is your last line of defense from internal threats and advanced attacks that may have slipped past your network, server and/or endpoint security solutions. Combining database management and security knowledge, best practices, advanced tools, and methods implemented at the database level is your best option.
Certain types of cloud databases, such as RDS, do not function like a traditional, full-database instance. They may be restricted environments that only provide access to a subset of information when compared to access with a full instance. This is because monitoring and management information is located in different places.
For example, with SQL Server®, you do not have direct access to the error log as you do in a traditional full-access instance so Amazon exposes access to the error log in a special way. This means you must adjust your monitoring strategy to account for this.
Another example is that certain performance indicators are not exposed in the same manner within RDS as they are in a full-access instance. CPU metrics, which you might query using Windows® Management Instrumentation (WMI) or perfmon, are exposed through Amazon’s application program interface (API) and dashboards instead.
Finding a cloud database monitoring solution that takes these variations into account for different types of cloud installations, accounting for the differences between EC2, RDS, Azure, and Google instances can give you peace of mind.
Cloud Migration Strategies
Cloud migration strategies differ based on the cloud environment. With RDS for example, you do not have access to the database’s underlying operating system (OS), cannot use the OS as part of your cloud migration strategy, and need to migrate in a different way. For example, some features that might be used for a migration are not available in an RDS instance, including restore from a backup (.BAK) file, log shipping, replication, etc. Use alternate scripting and data migration techniques to accomplish these types of migrations.
You can hot add CPU and memory resources but you cannot hot add cloud storage. If you run out of storage space, you need to spin up a new instance and migrate your entire environment. As a result, you should right size your environment with future growth in mind before you migrate your database(s) to the cloud.
Use a capacity and modeling planning service to help plan for growth. This reduces the need to again migrate your databases if storage runs short.
Ntirety Cloud Database Managed Services can help address all of these challenges by providing your business with a cohesive database strategy to simplify the migration, on-going management, and monitoring of your databases in a hybrid, private, or public cloud to reduce total cost of ownership (TCO), increase your return on investment (ROI), and improve database performance, access, protection, compliance, availability, and scalability.
