Choosing a storage class

1. Choosing a storage class

Let's explore the decision tree to help you find the appropriate storage class in Cloud Storage. If you will read your data less than once a year, you should consider using Archive storage. If you will read your data less than once per 90 days, you should consider using Coldline storage. If you will read your data less than once per 30 days, you should consider using Nearline storage. And if you will be doing reads and writes more often than that, you should consider using Standard storage. You also want to take into account the location type: Use a region to help optimize latency and network bandwidth for data consumers, such as analytics pipelines, that are grouped in the same region. Use a dual-region when you want similar performance advantages as regions, but also want the higher availability that comes with being geo-redundant. Use a multi-region when you want to serve content to data consumers that are outside of the Google network and distributed across large geographic areas, or when you want the higher data availability that comes with being geo-redundant. If your data has a variety of access frequencies, or the access patterns for your data are unknown or unpredictable, you should consider Autoclass. The Autoclass feature automatically transitions objects in your bucket to appropriate storage classes based on the access pattern of each object. Even if a different storage class is specified in the request, all objects added to the bucket begin in Standard storage. The feature moves data that is not accessed to colder storage classes to reduce storage cost. Data that is accessed is also moved to Standard storage to optimize future accesses. When object data is read, the object transitions to Standard storage if it's not already stored in Standard storage. Autoclass simplifies and automates cost saving for your Cloud Storage data. When enabled on a bucket, there are no early deletion charges, no retrieval charges, and no charges for storage class transitions. For more information, view the storage classes documentation. So far we have only considered unstructured data. Before we look at unstructured data, let's explore a high-performance, fully managed file storage offering; Filestore.
