This blog will cover SAA-C02 exam must have knowledge: AWS Storage Gateway.
Official Site links:
1. Storage Gateway supports three key hybrid cloud use cases – (1) Move backups and archives to the cloud, (2) Reduce on-premises storage with cloud-backed file shares, and (3) Provide on-premises applications low latency access to data stored in AWS.
2. The File Gateway enables you to store and retrieve objects in Amazon S3 using file protocols such as Network File System (NFS) and Server Message Block (SMB). Objects written through File Gateway can be directly accessed in S3.
3. The Volume Gateway provides block storage to your on-premises applications using iSCSI connectivity. Data on the volumes is stored in Amazon S3 and you can take point in time copies of volumes which are stored in AWS as Amazon EBS snapshots. You can also take copies of volumes and manage their retention using AWS Backup. You can restore EBS snapshots to a Volume Gateway volume or an EBS volume.
There are two types of Volume Gateway:
- Cached Volume: By using cached volumes, you can use Amazon S3 as your primary data storage, while retaining frequently accessed data locally in your storage gateway. Cached volumes minimize the need to scale your on-premises storage infrastructure, while still providing your applications with low-latency access to their frequently accessed data.
- Stored Volume: By using stored volumes, you can store your primary data locally, while asynchronously backing up that data to AWS. Stored volumes provide your on-premises applications with low-latency access to their entire datasets. At the same time, they provide durable, offsite backups.
4. Usually will be compared With AWS DataSync.
Those are some important points about AWS Storage Gateway which must to be kept in mind for SAA-C02 exam.
