Cloud migration continues to grow dramatically as more and more companies move to the cloud. But not all organizations are successfully able to reap the benefits of it. According to the 2020 IDG Cloud Computing Study, 94% of the respondents found it challenging to take full advantage of the public cloud.
Many organizations face unsuccessful cloud migration due to underestimated performance and cost problems. Monitoring and analysis can help detect such issues early on and resolve them before it’s too late. Applications and workloads should be monitored at every stage of migration- while running on-premises, during migration, and while running on the cloud post-migration.
In this article, we will discuss best practices and tips for monitoring the right way to make your cloud migration a success.
5 Tips for Monitoring a Cloud Migration
Monitor at each phase of cloud migration
Cloud migration efforts of an organization fail when monitoring is done post-migration in the new cloud environment. But for successful cloud migration, it is vital to apply monitoring at all the stages, namely: Plan, Migration, and Run.
The planning phase mainly involves creating baselines for performance comparison. Establishing pre-migration baselines helps you gain an in-depth understanding of the workloads and validate their performance on-premise. During migration, careful monitoring of applications’ behavior can help troubleshoot issues. And after migration, while running all the workloads and applications on the cloud, monitoring helps validate that applications perform as expected and all SLAs are met.
Create baselines for performance comparison before, during, and after migration
It is crucial to establish baselines against which you can compare performance for all the stages, including before, during, and after migration. It enables continuous monitoring and makes sure that no matter what changes you make in infrastructure, applications, or platform, the user experience does not suffer but improves it. In addition, it helps in identifying potential roadblocks or issues and troubleshoot them.
It is also vital that you consider all the new variables introduced by cloud migration, such as load balancing, network latency, etc., and create baselines for them. The baseline should be established for anything that cloud migration might affect and even for the metrics currently working well.
Set up your cloud environment with monitoring built-in
While setting up and launching your cloud environment, you can leverage the cloud provider’s resource management services, for instance, AWS CloudFormation and Azure Resource Manager. Such services enable integrations automatically that help you track the performance of your cloud infrastructure. Resource management tools have many features that allow for easy monitoring. For example, you can add tags to the services and infrastructure you launch in the cloud environment.
The most important lesson learned from cloud migration experiences by organizations is that application security monitoring is a must during and after the migration process. It helps you spot security threats or vulnerabilities and address them early on to avoid any undue stress. It also helps ensure that all the security and compliance requirements are met. It is essential that you monitor infrastructure configurations that are actively accessing different services like internal traffic, host open ports, and instance processes. In addition, monitoring API hits per second can also help indicate a distributed denial of service (DDoS) attack.
Monitor costs to measure the business value of your cloud migration
The majority of organizations adopt the cloud and migrate to reduce costs. But incorrect implementation of cloud resources may lead to cost overruns and losses. Thus, tracking and monitoring your cloud costs is crucial to ensure that your move to the cloud leads to a measurable business value and impact. You can leverage tools offered by your cloud provider to gain visibility into your costs. For example, AWS Billing natively integrates into your pipeline, monitors costs, and visualizes data on customized dashboards.
A complete and early monitoring of your workloads can make your cloud migration fast, seamless, and successful. At the higher levels, it can also help you adopt new cloud services or practices with speed, confidence, and accuracy. And to make it easier, major cloud providers also offer free tools that assist with monitoring and analysis.
The above list is not definitive, but we hope the monitoring tips will prove helpful to your cloud migration project.
