Having the right blend of encryption, key storage, and authentication services is critical for protecting your cloud-hosted data.

Fortunately, with the breadth of data security services IBM Cloud offers, you have the tools at your disposal you’ll need to cover your bases. Now the question becomes — which service blend is right for my solution?

To make answering this question easier, we’ve put together this blog to give you a consolidated view of the portfolio to reference when making this critical decision. The following sections outline the services and software that IBM Cloud offers for data protection, a mapping to key use cases, and an overview of the services and their key attributes.

Service overviews

As you plan your data protection strategy, some differences between services to consider include the level of data isolation that your workload requires. For a higher level of security and control, your business might benefit from the data isolation that a single-tenant offering provides, such as Secrets Manager or Hyper Protect Crypto Services. You might also decide that the lower costs and scalability benefits of a multi-tenant service, such as Key Protect and Certificate Manager, are better suited to your needs.

Optimize observability with IBM Cloud Logs to help improve infrastructure and app performance

5 min read - There is a dilemma facing infrastructure and app performance—as workloads generate an expanding amount of observability data, it puts increased pressure on collection tool abilities to process it all. The resulting data stress becomes expensive to manage and makes it harder to obtain actionable insights from the data itself, making it harder to have fast, effective, and cost-efficient performance management. A recent IDC study found that 57% of large enterprises are either collecting too much or too little observability data.…
