Organizations choose which data and apps should reside on which components of hybrid cloud infrastructure using a hybrid cloud approach. What goes on in public cloud infrastructure and what goes on in cloud infrastructure are defined by hybrid cloud strategies.
Although there are many different definitions of hybrid cloud architecture, two key elements are infrastructure as a service, or IaaS, for public clouds, and private clouds, including on-premises data centers that may or may not use cloud platforms.
According to McAfee’s 2019 Cloud Adoption and Risk Survey, the average organization used an average of 1,935 cloud services, demonstrating the growing adoption of public cloud services by businesses as part of their overall IT strategy.
A hybrid cloud strategy, seen from a higher perspective, combines a private cloud with one or more public cloud providers, allowing them to share and move applications and data through a wide area network (WAN).
Disaster recovery and business continuity (DR/BC) is one of the main applications for a hybrid cloud, where enterprise data and snapshots are saved in the public cloud for quick recovery. Another well-liked tactic is cloudbusting, which involves using public cloud services when periods of high consumption necessitate increased processing capacity for applications, hence avoiding the need to over-provision equipment that would only occasionally be used.
How is a Hybrid Quality Strategy Built?
Enterprises must evaluate their current apps, both legacy and new, to see if any of them would be suitable for use in a public cloud before implementing a hybrid cloud computing strategy. Demands for security, regulatory, conformance, and data governance requirements should be taken into account, as well as the cost of virtual machine (VM) subscriptions in comparison to the amortized costs of on-premises infrastructure and the technological advantages of potential cloud providers, such as the simplicity of integrating hosted and on-premises applications and data.
A hybrid cloud strategy must be based on the common, consistent cloud architecture that spans both public and private clouds, trying to simplify orchestration between both, such as VMware orchestration techniques for VMs and Kubernetes for containerized applications. Hybrid cloud strategies include seamless workload portability between private and public clouds.
The transition to a hybrid cloud environment will be significantly facilitated for businesses that embrace standard architecture embracing both public and private clouds. Of course, some applications are more portable than others. For example, moving a web front-end application to the cloud is much simpler than moving a heavily used database, and once data is moved into the cloud, many cloud service providers (CSPs) impose egress charges on it when it is taken off the cloud to be processed elsewhere. These fees can quickly add up and cause sticker shock on quarterly invoices.
Accenture provides a “seven Rs” process that includes the following when deciding on a hybrid cloud strategy:
Retire: When evaluating applications, see whether any can be dropped.
Retain: Keep in the private cloud any applications that cannot be migrated but are still required.
Replace: Check to see if commercial or SaaS applications can take the place of custom-built ones.
Rehost: Use CSP advances to rehost data and applications with low friction.
Replatform: Replatform a program if necessary if only minor changes are required.
Refactor: Refactoring is the process of making significant modifications to an application.
Reimagine: Consider cloud-native, microservices-based technologies when redesigning applications to increase business value and boost IT performance.
What difficulties does a hybrid cloud strategy face?
When creating a hybrid cloud strategy, there are some obstacles to overcome. For the purpose of identifying risks and exposing hidden value to the corporation, organizations should begin by performing a detailed and in-depth audit of their current applications and data.
Multiple Hybrid Cloud Challenge?
Every hybrid cloud environment must have both public and private clouds by definition, and many hybrid cloud environments incorporate numerous public cloud providers. It can be difficult to decide which applications are best suited for which cloud, and it may take the program being rehosted for “hidden” costs to become apparent before it is clear how much more expensive it is to run an application in the public cloud than on-premises.
When deployments do not go exactly as anticipated, there is always room for finger-pointing, just like in any environment with several environments. The on-premises private cloud team and one or more public cloud teams must be committed to working closely together to identify the core cause of issues in a hybrid cloud system.
Cloud cost uncertainty:
Integrating private and public cloud operations might result in unanticipated costs for extra software licenses, fees for unused virtual machines, and data egress fees, to mention a few. Enterprises should design data flows and application usage when developing a hybrid cloud strategy to reduce CSP costs while maximizing performance and overall cost-effectiveness.
Challenges with scalability:
The ability to grow private cloud apps that are protected by on-premises firewalls can be challenging, which is one of the main reasons for using a hybrid approach. Make sure the apps are designed to access public cloud resources when necessary while designing for cloud bursting to the public cloud.
There are no miracle cures:
To facilitate a hybrid cloud strategy, organizations need to discover the appropriate technologies and platforms. In the majority of situations, both for on-premises infrastructure and the public cloud, there will be various vendors, integrations, and technologies used. Instead of attempting to fit every application into the same tool set, choose the appropriate tools for each use case.
What advantages can a hybrid cloud strategy offer?
Here are the results of a study conducted by the international technology company Cloudnexion that outlines the top five advantages of using a hybrid cloud approach.
Data protection: Backup, recovery, and enterprise data protection was the first practical use case for the public cloud. Businesses can use the on-site data protection solutions they already have or delegate data security to system integrators who handle backups, snapshots, BC/DR, and recovery for a set fee, guaranteeing legal requirements like HIPAA, PCI, and GDPR are strictly adhered to. The time it takes to recover lost data and RPO/RTO can be decreased from days or hours to seconds by switching from tape backup to cloud backup.
Innovation: Using a public cloud partner can help an application modernization plan, modeling new IT infrastructure and apps. A hybrid cloud strategy allows R&D and development staff to experiment without the requirement to purchase expensive infrastructure for a testbed.
Even if the ultimate goal is to transition new apps to on-premises infrastructure, they can be quickly launched in the public cloud once they receive the all-clear.
Business Nimbleness: The IT catchphrase has changed over the last ten years from “do more with less” to “do everything with nothing.” The capacity to prototype and spin up new apps or to create an improved user experience for a mobile application might be crucial to the success or failure of a corporation when launching a new analytics application. A hybrid cloud strategy fosters corporate agility and bottom-line value by utilizing flexibility, rapid time to market, and cost advantages.
Scalability: Even the most well-established businesses may see increases in demand, whether as a result of holiday shoppers, an Oprah mention, or a successful product launch. By absorbing surges with public cloud resources that can be automatically spun up when demand increases and spun down when demand decreases, hybrid clouds can do away with the requirement for exact resource utilization estimates.
Time-to-Market: Many firms are forced to deal with a lengthy procurement cycle that can last several months. With less risk, IT and line of business (LOB) teams may quickly spin up new infrastructure to fulfill development, test, or deployment needs instead of waiting for capital acquisition approvals to launch a new business initiative.
