Interruptions to business processes can have major consequences, affecting all aspects of business operations and causing severe losses, both financial and reputational. The more sophisticated technology becomes, the more effort it requires to maintain continuous productivity and reliable performance.<\/p>\n

For enterprises, downtime often translates into financial losses. According to a survey by Information Technology Intelligence Consulting, for 44% of midsize businesses and large enterprises, just one hour of downtime can cost more than one million dollars<\/a>.<\/p>\n

IT downtime has many causes, from natural disasters destroying physical equipment to human error and cyberattacks. To prevent or at least mitigate the consequences of IT outages, businesses invest billions in disaster recovery (DR) measures. IBM calculated<\/a> that in 2023, global spending on cybersecurity alone amounted to US$219 billion.<\/p>\n

Recognizing the importance of disaster recovery measures, the business community is setting its sights on cloud technologies. Compared to traditional DR strategies, cloud-based solutions<\/a> offer far more reliable protection against most threats. In this post, we get into the details of disaster recovery in the cloud and outline a basic approach to building an effective cloud disaster recovery plan.<\/p>\n

What is disaster recovery in the cloud?<\/h2>\n

Any DR strategy boils down to setting up redundant resources to back up critical data and applications, enabling their restoration in the event of a disaster. Traditional DR plans involve physical data centers and storage capacities replicating data to protect it and enable access to it to ensure business continuity.<\/p>\n

Conceptually, cloud disaster recovery serves the same purpose of replicating and backing up important data to ensure its availability in the event of a disaster. The main difference is that with cloud DR, there are no physical servers directly involved in data replication. Instead, mission-critical data is stored either in a public cloud or on a dedicated provider\u2019s cloud platform.<\/p>\n

Increasing adoption of cloud technologies and their use for storing data as a disaster recovery measure has led to the emergence of a dedicated area of cloud computing, disaster recovery as a service (DRaaS), in which cloud providers host business infrastructure. DRaaS keeps gaining traction and, according to Markets and Markets<\/a>, is expected to reach a market value of US$26.5 billion globally by 2028.<\/p>\n

Cloud disaster recovery vs. traditional disaster recovery<\/h2>\n

Whether to invest in disaster recovery is no longer a question: an increasing number of business processes depend on information technology. Instead, businesses have to decide whether to opt for traditional on-premises backup infrastructure or for cloud solutions.<\/p>\n

Both approaches have their pros and cons that need to be weighed carefully when choosing the DR strategy for your business. Your choice between an on-premises setup and cloud disaster recovery as a service should take into account both the benefits you expect to receive and your organization\u2019s limitations, such as your budget, business flows, and available workforce and skills.<\/p>\n

Let\u2019s compare the main factors that may influence your choice.<\/p>\n

\n\n\n\n\n\n\n\n\n\n\n\n
<\/th>\nOn-premises<\/th>\nCloud<\/th>\n<\/tr>\n
Ease of launch<\/th>\nDR configuration requires setting up redundant physical infrastructure, which needs to be done by technical IT staff.<\/td>\nIn-house IT staff only needs to configure connectivity to the cloud provider, while the actual setup is done on the provider\u2019s side.<\/td>\n<\/tr>\n
Customization<\/th>\nPhysical infrastructure may be selected according to specific business requirements; however, subsequent changes may be difficult and expensive.<\/td>\nWhile there may be certain limitations resulting from the provider\u2019s capacities, cloud solutions offer flexibility both in the selection of available options and infrastructure updates.<\/td>\n<\/tr>\n
Infrastructure costs<\/th>\nThere are high upfront costs, including equipment and the space to host it. Ongoing costs may be high, too, covering power, cooling, and equipment maintenance.<\/td>\nDRaaS involves an affordable initial investment while providing a full range of cloud backup and disaster recovery services. Most cloud providers offer flexible pay-as-you-go pricing models, allowing you to pay only for what you consume.<\/td>\n<\/tr>\n
Scalability<\/th>\nScalability is limited to the capacity of physical equipment. Scaling requires additional investments in hardware and its installation.<\/td>\nCloud solutions easily scale up and down based on the actual workload and business growth. You only pay for the cloud computing resources you use in your DR activities.<\/td>\n<\/tr>\n
Reliability<\/th>\nLocal DR infrastructure has the same vulnerabilities as the primary infrastructure. Physical servers can be affected by network outages, power failures, or cyberattacks.<\/td>\nWith geographically distributed coverage, cloud networks provide consistent service and have better failover options.<\/td>\n<\/tr>\n
Uptime and data recovery<\/th>\nPhysical infrastructure may have slower data recovery, resulting in more unpredictable downtime.<\/td>\nWith always-on replication used in DRaaS solutions, data recovery is significantly faster.<\/td>\n<\/tr>\n
Latency<\/th>\nThe proximity of on-site servers may reduce the latency of the DR infrastructure.<\/td>\nCloud DR solutions may have latency issues caused by the geographic location of the particular cloud server.<\/td>\n<\/tr>\n
Control<\/th>\nWith DR resources in your direct ownership, you may have stronger control over the infrastructure.<\/td>\nThe cloud provider primarily controls the infrastructure, increasing the level of dependency on their operation.<\/td>\n<\/tr>\n
Maintenance<\/th>\nBoth routine maintenance and emergency response require qualified IT staff to be present to ensure business continuity.<\/td>\nRegular maintenance and emergency response are the responsibility of the cloud provider. Moreover, the cloud services provider has more opportunities to implement automation and self-healing practices to secure consistent operations than its users.<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n

Creating a cloud-based disaster recovery plan<\/h2>\n

\"A<\/p>\n

In designing your cloud DR strategy and plan, assume that incidents will inevitably happen. The point is to prevent or minimize their effect on your business and secure the service-level agreements (SLAs) you have committed to. A successful DR plan should provide a reliable method for quickly recovering your data and restoring business continuity.<\/p>\n

Let\u2019s walk through the steps of designing a working DR plan. Note, however, that a cloud-based disaster recovery approach requires certain special IT knowledge and experience of working with cloud technologies. While the bulk of the DR infrastructure is set up by the cloud provider, local IT engineers should configure the necessary connectivity.<\/p>\n

1. Evaluate your infrastructure and define potential risks<\/h3>\n

Start planning your disaster recovery by conducting an inventory of your assets and data that need to be protected from failures and attacks. Knowing what you have, where everything is stored, and how critical each piece of data is will help you set priorities in designing recovery solutions for your infrastructure.<\/p>\n

At the same time, estimate potential risks to your assets. Include all possible natural and human-induced incidents, such as natural disasters, power failures, data breaches, and other cyberattacks in your research. Knowing the risks helps you visualize possible redundancy and replication methods that can secure a quick recovery.<\/p>\n

2. Analyze business impact<\/h3>\n

Once you have identified your strategic assets and evaluated the potential risks to them, analyze how disasters could affect your operations and service. Start with reviewing the service-level objectives (SLOs) and service-level agreements (SLAs) you have committed to in your arrangements with clients. Based on these, you can determine reliability targets that will help you design your cloud DR strategy:<\/p>\n
