This means you don’t have to pay for unused compute capacity just to add more storage. ![]() That pattern separates compute and storage by enabling independent scaling of both to match the use case. A common pattern is to run queries that span both the frequently accessed “hot” data stored locally in Amazon Redshift and the “warm/cold” data stored cost-effectively in Amazon S3. You do so using external tables, without having to ingest the data into Amazon Redshift first. In other words, Amazon Redshift Spectrum enables you to use the same ANSI SQL syntax of Amazon Redshift on the data that is stored in an Amazon S3 data lake. It uses a distributed, massively parallel processing (MPP), shared-nothing architecture that scales horizontally to meet usage requirements.Īmazon Redshift Spectrum is a feature of Amazon Redshift that extends the analytic power of Amazon Redshift beyond the data that is stored on local disks in the data warehouse. About Amazon Redshift and Redshift SpectrumĪmazon Redshift is a petabyte scale, fully managed data warehouse service on AWS. AWS KMS is integrated with AWS CloudTrail, a service that provides a record of actions performed by a user, role, or AWS service in AWS KMS. These customer-managed CMKs enable you to have full control over the access permissions that determine who can use the key and under which conditions. In these cases, you can create and manage your own CMK that AWS services such as Amazon Redshift can use on your behalf. In some cases, you might need direct control over the lifecycle of a CMK or want to allow other accounts to use it. You can track the usage of the key, but it’s managed by the service on your behalf. When deciding to encrypt data in a service such as Amazon Redshift, you can choose to use an AWS-managed CMK that Amazon Redshift automatically creates in KMS. This integration means that you can easily use customer master keys (CMKs) to control the encryption of the data you store within these services. AWS KMS uses FIPS 140-2 validated cryptographic modules to protect the confidentiality and integrity of your master keys.ĪWS KMS is seamlessly integrated with most AWS services. You can create, import, rotate, disable, delete, define usage policies, and audit the use of encryption keys used to encrypt your data. With AWS Key Management Service (AWS KMS), you can have centralized control over the encryption keys used to protect your data at rest. About AWS Key Management Service (AWS KMS) The sample dataset is encrypted at rest using AWS KMS-managed keys (SSE-KMS). This post shows a step-by-step walkthrough of how to set up a cross-account Amazon Redshift COPY and Spectrum query using a sample dataset in Amazon S3. ![]()
