With the current pandemic situation globally, we as an\u00a0IT business\u00a0are responsible for taking appropriate measures to ensure everyone\u2019s safety and as well ensure the Business continues as usual.<\/p>\n<p>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\u00a0Datacenters,\u00a0Office Networking,\u00a0Active Directory services,\u00a0Hardware and Appliances\u00a0and more, which form key components of\u00a0<strong><a href=\"https:\/\/www.happiestminds.com\/services\/managed-infrastructure-services\/\">IT infrastructure<\/a><\/strong> and<strong>\u00a0<\/strong>form backbone of business continuity.<\/p>\n<p>But as we all know, no\u00a0IT systems\u00a0are 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\u00a0IT 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)\u00a0solutions\u00a0form a critical component to ensure Business continues in case of any disaster. These ensure operational resilience in the event of any interruptions or failures.<\/p>\n<p>To address the problem stated above, we would need to have a robust and cost-effective\u00a0BC\/DR strategy\u00a0in place, which brings us to the point on how cloud services can be used as an effective\u00a0BC\/DR strategy solution.<\/p>\n<p>Cloud service providers render more flexible service offerings which help us to minimize cost and maximize benefits.<\/p>\n<p>We can make use of a variety of services such as backup solutions,\u00a0traffic management,\u00a0infrastructure as a Code, gives the ability to ramp up the\u00a0infrastructure\u00a0quickly, in a\u00a0BC\/DR scenario\u00a0giving\u00a0end-user\u00a0full and seamless performance to\u00a0end-user.<\/p>\n<p>Customers can also use\u00a0<strong><a href=\"https:\/\/www.happiestminds.com\/services\/cloud-data-center-advisory-transformation\/\">cloud\u00a0<\/a><\/strong>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.<\/p>\n<p>With\u00a0Cloud Services,\u00a0we also have an additional benefit of\u00a0Pay-per-Use,\u00a0which helps us to minimize cost and expenditure on\u00a0DR infrastructure.<\/p>\n<p>Before considering\u00a0<a href=\"https:\/\/www.happiestminds.com\/services\/cloud-computing\/\"><strong>Cloud Services<\/strong><\/a>\u00a0as a\u00a0BC\/DR solution,\u00a0any organization need to have an impact analysis to understand and establish key objectives such as:<\/p>\n<ul>\n<li>RTOs: Recovery Time Objective<\/li>\n<li>RPOs: Recovery Point Objective<\/li>\n<li>DR strategy<\/li>\n<\/ul>\n<p>Once the above parameters are defined, we can investigate various cloud models to help continuously deliver dependable\u00a0infrastructure.<\/p>\n<p>Few well-known\u00a0cloud models\u00a0that help in\u00a0BC\/DR\u00a0strategies are listed below.<\/p>\n<ol>\n<li>Hot site or active\/active setup<\/li>\n<\/ol>\n<p>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.<\/p>\n<ol start=\"2\">\n<li>Warm or cold site active\/passive thisscenario, we will have the same amount of resources provisioned on\u00a0the Cloud\u00a0but will be in a standby mode (powered off), during the disaster, we can quickly bring up the resources online and serve workloads.<\/li>\n<\/ol>\n<p>The solution also helps in cost savings as we can make use of\u00a0Pay 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.<\/p>\n<ol start=\"3\">\n<li>Workload-based disaster recovery or business continuity<\/li>\n<\/ol>\n<p>Might not span the entire\u00a0infrastructure\u00a0but 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\u00a0the Cloud,\u00a0and we will pay for minimal resources on the\u00a0Cloud.<\/p>\n<ol start=\"4\">\n<li>Backup-based recovery<\/li>\n<\/ol>\n<p>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.<\/p>\n<p>We can use solutions like storage gateway to regularly backup data from on premise\/ enterprise architecture onto the\u00a0Cloud, which helps us in recovery in case of On-Prem failures. This process is a bit slower and depends on various factors as\u00a0Network Bandwidth\/CSPs SLA\u00a0and more.<\/p>\n<p>High-Level Benefits of Cloud-Based BC\/DR vs Traditional Approaches<\/p>\n<p><strong>Some of the key benefits of using a reliable, highly available\u00a0cloud-based\u00a0service for\u00a0BC\/DR\u00a0of systems include<\/strong>:<\/p>\n<ul>\n<li>Effectively Unlimited Scalability: As it is well known,\u00a0cloud services\u00a0offer unlimited elasticity and scalability on infrastructure, which helps us leverage this and scale up the resources on-demand whenever there is a need. This is very challenging when it comes to traditional\u00a0IT infrastructure.<\/li>\n<li>Cost-Effective: Consumers pay only for the service what they use. This helps to use cloud options and minimize cost on DR strategies effectively.<\/li>\n<li>Availability and Resilience: with multiple options available on the\u00a0Cloud\u00a0such as\u00a0Multi-Availability Zone,\u00a0Multi-Region,\u00a0Auto-Scaling\u00a0and we need not worry about availability and resiliency of\u00a0infrastructure\u00a0residing on the\u00a0Cloud.<\/li>\n<li>Faster Provisioning\/De-Provisioning:\u00a0Provisioning and de-provisioning of infrastructure on Cloud is easy and can be automated. This gives a very great advantage\u00a0of faster infrastructure provisioning\/de-provisioning during\/after the DR scenario.<\/li>\n<li>No (Minimal) Systems BC\/DR Expertise Required:\u00a0There is a noticeable reduction in the effort and the skill required from the consumer when compared to the traditional\u00a0BC\/DR processes. This is even more valid for<\/li>\n<li>\u00a0data recovery, and redundancy for\u00a0cloud-based\u00a0systems as the CSP will make sure that the automated fail-over practices exist for protecting their systems.<\/li>\n<\/ul>\n<p><strong>Security on Cloud<\/strong><\/p>\n<p>One of the major concerns for any IT industry is security and especially when it is not hosted on your environment, such as\u00a0a public cloud.<\/p>\n<ul>\n<li>Any\u00a0cloud service\u00a0provider, we have a shared responsibility model, when\u00a0cloud service\u00a0providers are responsible for securing the backend\u00a0IT infrastructure\u00a0and Customers are responsible for securing their applications, VMs and more.<\/li>\n<li>In cloud infrastructure is already complaint with various industry-based\u00a0Security\u00a0standards such as\u00a0PCI-DSS,\u00a0HIPAA,\u00a0ISO\u00a0and more. Cloud Service Providers also offer various services which help the customer to secure their\u00a0data\u00a0residing on\u00a0cloud infrastructure.<\/li>\n<li>Can make use of services such as\u00a0encryption\u00a0with\u00a0CMKs, vaults such as secrets-managers to encrypt and protect the data.<\/li>\n<li>Options are also available to proactively\u00a0monitor <strong><a href=\"https:\/\/www.happiestminds.com\/services\/governance-risk-and-compliance\/\">compliance\u00a0<\/a><\/strong>and\u00a0<strong><a href=\"https:\/\/www.happiestminds.com\/services\/it-security-services\/\">security\u00a0<\/a><\/strong>of\u00a0cloud infrastructure\u00a0with various multiple services.
