Kubernetes is the number one container orchestration platform, as it’s suitable for deployment, scaling, and management of containerized applications. Several managed cloud-based services are available for Kubernetes, but are they right for your situation? Let’s look at the benefits and drawbacks of these services.

Limitations of a Managed Cloud Database Service

With the advent of cloud computing, several managed services for databases have become available. Whether to use a managed cloud database service from a cloud provider depends on several factors, and it may not be the best choice for everyone. Knowing the limitations can help you decide whether it makes sense for you.
