You can also achieve a better database performance with EBS volumes of EC2 instances than with Amazon S3 storage. Data can be copied with high speed from one EBS volume to another. Advantages: EBS can be used for high-performance workloads.Below are some advantages and disadvantages of using EBS volumes for backup and restore. For example, you can replicate databases from on-premises servers or VMs to EC2 instances and perform almost instant failover when you need to recover from a disaster.ĮBS volumes used by EC2 instances provide high-speed block storage. Resuming the operation of applications and servers using replicas requires less time than using backups (that is, lower RTO). In a disaster scenario, replication to EC2 is preferable to backups. To be prepared for such a scenario, you should migrate local workloads to the cloud using backups or replicas as part of a disaster recovery plan. Using Amazon EC2 for Recovery of WorkloadsĪmazon EC2 instances can be used for cloud recovery of on-premises virtual machines when a local production data center becomes unavailable. Object-based storage allows the use of versioning, which is a useful feature for data recovery. Data is stored in buckets as objects and not as blocks. The container used to store data is called a bucket. Amazon S3 (Simple Storage Service) is the AWS object storage service.You can choose between hard disk drives (HDD) and solid-state drives (SSD) for EBS volumes. EBS volumes are connected to instances and store the primary data of these instances. The container that stores instance data is called an EBS (Elastic Block Storage) volume, which is the equivalent of a virtual disk.ĮBS volumes are classified as block storage as the basic unit of data storage is a block. Amazon EC2 (Elastic Cloud Computing) instances are virtual machines running in the AWS cloud on AWS servers and in AWS data centers.But how and when to use them? Let’s start by going over what the two AWS services offer. Cloud storage, including Amazon S3 and EBS volumes in Amazon EC2 instances can be used as offsite storage for backup data. DISCOVER SOLUTION Why Use AWS for Data BackupĪccording to the 3-2-1 backup rule, you should maintain at least three copies of critical data, one of which should be stored offsite.
