Even a minimal interruption of service can mean disaster for an organization, implying thousands of dollars in data loss. A disaster can be caused by a security attack, a natural disaster or human error. Business continuity is critical for any company in the cloud. A solid disaster recovery plan help organizations stay up in the event of failure or attack.<\/span><\/p>\n One of the leading cloud vendors, Amazon Web Services (AWS), provides its users with features to help them build their own Disaster Recovery Solution. In this article, I aim to cover what is a Disaster Recovery Plan (DRP) for AWS and I\u2019ll offer 10 tips to leverage the functions in your AWS console to prevent and recover from a disaster.<\/span><\/p>\n Deploying an on-premises disaster recovery solution usually involves high costs of implementation and maintenance. Therefore, many companies leverage the disaster recovery tools and solutions provided by their cloud vendors, such as\u00a0AWS\u00a0or Azure. These solutions may be offered by third-party vendors \u2014 for example, AWS partners with companies such as N2WS and Cloudberrylab that offer disaster recovery solutions tailored to AWS.<\/span><\/p>\n AWS users can derive several benefits from developing a recovery plan and having it ready such as:<\/span><\/p>\n What resources compose the core of your business? A Business Impact Analysis (BIA) can help give you a picture of which areas can become more affected in the event of a threat. It also can guide you to preview the potential impact of a disaster in operations.<\/span><\/p>\n You should know how much system downtime your organization can afford before suffering irreparable monetary losses. Therefore, calculating your recovery time objective is critical for a successful recovery plan. Moreover, you need to calculate how much data loss your organization can absorb before incurring too much damage \u2014 that is the recovery point objective. For example, if losing 4 hours of data will cause too much damage, then you need to account for an RPO of much less than 4 hours.<\/span><\/p>\n There are four main recovery methods you can choose according to your organization requirements and preferences:<\/span><\/p>\n For example, you can implement detective measures such as server and network monitoring software. Corrective measures as remediation tools can help restore a system after a disaster.<\/span><\/p>\n Schedule testing while developing your DRP can help you catch flaws before you need to implement the plan. This can ensure your plan is well oiled before a disaster or threat occurs.<\/span><\/p>\n You should update your plan on a regular basis, to catch up with system changes. In the aftermath of a threat, this forms part of lessons learned, refining the plan to prevent further attacks or failures.<\/span><\/p>\n Scheduling regular backups of what you have stored on Amazon EC2 and EBS volumes could be insufficient to face a disaster. You need to have quick access to the data in the event of a disaster. A detailed and up-to-date\u00a0AWS disaster recovery plan\u00a0can help you recover and restore the backup data from the cloud environment with minimal downtime.<\/span><\/p>\n While developing your plan you need to decide where the critical data will be stored. To avoid getting your entire system knocked offline, you should distribute the data across different availability zones (AZ) around the world.<\/span><\/p>\n For example, you can use cross-region replication for S3. S3\u2019s duplicates the data to multiple locations within a region by default, creating high durability. However, this does not eliminate the risk of data loss in a given region. To prevent this, you can use the cross-region replication option, automating the copying of the data to a designated bucket in another region.<\/span><\/p>\n You can also use global tables in DynamoDB to deploy a multi-region multi-master database. This spreads the changes across several tables. Since the data is distributed in different regions, minimizes the risk of data loss.<\/span><\/p>\n Needless to say, you should keep your root passwords and credentials secure and hidden from non-authorized users, even disabling the programmatic keys once they are used, to prevent internal threats. Setting a multi-factor authentication solution can ensure the administrator and programmatic privileges don\u2019t fall into malicious hands.<\/span><\/p>\n While it may be tempting to implement all steps of a disaster recovery plan in-house, smaller companies lacking a dedicated IT team find it easier to use a third-party solution. Disaster recovery-as-service companies help organizations to develop, implement, and maintain their DRPs, enabling them to focus on growing their businesses.<\/span><\/p>\n Let\u2019s say you migrated to the cloud using the rehosting method and you use EC2 instances for your application. There are several ways to begin leveraging AWS functions to develop a DR plan:<\/span><\/p>\n Summary<\/span><\/strong><\/span><\/p>\n Developing and implementing a disaster recovery plan for AWS requires a certain degree of ingenuity since AWS does not offer its own DR solution. However, the platform enables users to build a customized DR solution by repurposing some of the platform\u2019s features and tools. In this article, I\u2019ve aimed to give you some tips and tools to develop your own disaster recovery plan leveraging AWS environment.<\/span><\/p>\n Reference<\/span><\/strong><\/span><\/p>\n https:\/\/medium.com\/@eddies_47682\/10-tips-for-developing-an-aws-disaster-recovery-plan-a708f899a442<\/span><\/p>\n VTI Cloud<\/strong>\u00a0is an\u00a0Advanced Consulting Partner<\/a>\u00a0of AWS Vietnam with a team of over 50+ AWS certified solution engineers.
