How is this achievable? Simply put, hybrid cloud provides the best of all worlds by offering deployment options.
Many experts believe hybrid cloud will provide the most advantageous approach for organizations seeking both flexibility and control. Adopting a hybrid cloud environment will enable organizations to move applications, data, and other resources to the ideal cloud environment while preserving certain data and resources on-premises.
Key factors to consider when investigating a hybrid cloud approach:
Determine if applications are better suited for the public or private cloud. One proven approach is to have a Cloud Readiness Assessment done on your existing data center. The assessment is focused on 3 key areas that must be considered when looking to move to the cloud or deploy a hybrid cloud model.
1) What are the business drivers and potential challenges?
2) What service performance and availability are needed for each application?
3) What architecture and technology are used today?
The answers will help identify the applications and/or data sets that can be moved to the cloud.
Lower Time to Production
Utilize the flexibility of public cloud for DevOps. Organizations must become increasingly agile, as customer demands are always changing and evolving. Time to market is key for any industry! Software development has moved from waterfall to agile models of development. The impact on IT is to be more flexible and provide DevOps the flexibility to test new software codes without having to deploy a new hardware environment. The cloud provides the flexibility to scale on the fly and to remain agile as technical needs continue to evolve.
Leverage Existing Infrastructure and Resources
Over time, IT admins will work out which resources are better suited for in-house versus in the cloud. Part of the Cloud Readiness Assessment that I discussed earlier will help determine which applications can reside in the Cloud and on-premise. Tools like Sumo Logic provide real-time operations to rapidly identify problems, whether the application resides in the Cloud or on-premise, or both. Leverage the analytics to recognize patterns and trends and uncover problems and potential issues before they impact your customers.
Encrypting data at rest, in flight, and in the cloud are key to a successful hybrid cloud. Security concerns for the Cloud and on-premise have been at an all-time high, and I do not see this trend slowing down anytime soon. One key factor that needs to be considered is making sure that your data is secure. Solutions like Thales can provide options to encrypting data at rest, in flight, and bring your own key to the Cloud.
Understanding the latency of workloads across the Cloud & on-premise is key to understanding if network connection speed needs to be improved. Understanding the network connection between your users and the Cloud is very important. I recently spoke to a customer who had migrated a handful of applications to the Cloud on their own. They were considering moving everything back on-premise because of latency concerns. I asked about the network connection between their users and the Cloud: 250Mbps. We did a quick speed test and calculated what they will be upgrading to a dedicated network for cloud traffic.
Reduce overall risk by having applications and data across the Cloud and on-premise. High availability and resiliency are very important considerations for data centers. Leveraging the cloud and your on-premise data center can ensure high availability of your applications and data. To protect against outages in the cloud or on-premise, always ask “what if” and develop an approach for each, no matter how infrequent. Make sure that you test against each scenario to know how long it takes to recover and if there is any data loss.
Leveraging companies like Relus to provide a Cloud Assessment provides an in-depth view into your existing environment. Utilizing the information gathered will help create a path to migrate applications and data to the Cloud while assessing which applications & data need to reside on premise. Addressing the key factors for deploying a hybrid cloud will ensure a successful experience.
In my opinion, it would be foolish to not deploy a hybrid cloud model. Having the ability to pick and choose the Cloud and on-premise deployments allow for flexibility and cost savings that are more beneficial than using just the Cloud or on-premise data centers. The overall benefits of hybrid cloud are amazing.
