As we all know, the current situation of COVID-19 has made a massive impact on the Business of various industries and individuals. With the current pandemic situation globally, we as an IT business are responsible for taking appropriate measures to ensure everyone’s safety and as well ensure the Business continues as usual.
This results in limited employees available on-premises/office locations to take care of daily Business as usual activities to maintain IT and business continuity such as Datacenters, Office Networking, Active Directory services, Hardware and Appliances and more, which form key components of IT infrastructure and form backbone of business continuity.
But as we all know, no IT systems are 100% available and disaster-free. Emergencies can happen, systems can go down due to various factors such as an increase in load, power failure, hardware failure, climatic extremities and more. During these scenarios, it is also not very feasible or easy to scale up traditional IT infrastructure. But we as a business cannot take this as a reason to stop functioning and impact Business and customers. Hence business continuity and disaster (BC/DR) solutions form a critical component to ensure Business continues in case of any disaster. These ensure operational resilience in the event of any interruptions or failures.
To address the problem stated above, we would need to have a robust and cost-effective BC/DR strategy in place, which brings us to the point on how cloud services can be used as an effective BC/DR strategy solution.
Cloud service providers render more flexible service offerings which help us to minimize cost and maximize benefits.
We can make use of a variety of services such as backup solutions, traffic management, infrastructure as a Code, gives the ability to ramp up the infrastructure quickly, in a BC/DR scenario giving end-user full and seamless performance to end-user.
Customers can also use cloud offerings such as dedicated network connections, cloud-based directory, DNS services, storage services to have faster connectivity, resolution and Resilience which can help in reducing network delays, increased response times and data availability.
With Cloud Services, we also have an additional benefit of Pay-per-Use, which helps us to minimize cost and expenditure on DR infrastructure.
Before considering Cloud Services as a BC/DR solution, any organization need to have an impact analysis to understand and establish key objectives such as:
Once the above parameters are defined, we can investigate various cloud models to help continuously deliver dependable infrastructure.
Few well-known cloud models that help in BC/DR strategies are listed below.
This might be an expensive option, and a hot website/a perennially operational site would be required. But this gives an advantage of very minimal downtime and seamless business continuity.
The solution also helps in cost savings as we can make use of Pay as You Go model, in which we will be paying for services only when in use. This might have a smaller downtime as the cold site needs to be online before catering workloads.
Might not span the entire infrastructure but only needs to target certain mission-critical services or applications. This is a very cost-effective solution as only critical applications will be hosted on the Cloud, and we will pay for minimal resources on the Cloud.
This solution can be used for scenarios where there is no possibility of auto-healing and service downtime can be afforded up to a certain extent. Applications are still considered necessary for bringing up quickly without any business impact, adhering to the clearly defined backup policies when mentioned.
We can use solutions like storage gateway to regularly backup data from on premise/ enterprise architecture onto the Cloud, which helps us in recovery in case of On-Prem failures. This process is a bit slower and depends on various factors as Network Bandwidth/CSPs SLA and more.
High-Level Benefits of Cloud-Based BC/DR vs Traditional Approaches
Some of the key benefits of using a reliable, highly available cloud-based service for BC/DR of systems include:
Security on Cloud
One of the major concerns for any IT industry is security and especially when it is not hosted on your environment, such as a public cloud.
The Cloud, armed with better replication, stronger resilience, faster provisioning and perennial support, can be an impressive platform for our DR strategy, keeping cost in mind and ensuring seamless business run for end-users and customers.
