Como você pode virtualizar aplicativos de missão crítica?

To virtualize mission-critical applications: 1. Assess requirements and choose a reliable virtualization platform. 2. Implement resilient storage and prioritize security measures. 3. Establish backup and disaster recovery protocols. 4. Optimize performance and allocate resources efficiently. 5. Ensure licensing compliance and document configurations. 6. Implement monitoring tools for proactive issue identification. 7. Test and validate the virtualization setup regularly. 8. Stay informed about technological advancements for ongoing optimization.

Beyond avoid costs with virtualization, you need check the internal competences to support this new environment. The knowledge could be similar, but the new responsabilities are differents in comparsion of a on-premisses environment, like shared resources such processor, disks and memory.

To virtualize mission-critical applications in IT: -Assess Compatibility: Ensure the application is compatible with virtualization technology. -Choose the Right Platform: Select a robust virtualization platform that offers high availability, scalability, & security. -Plan for Resources: Allocate sufficient computing resources (CPU,memory,storage) for optimal performance. -Implement HA: Set up failover clustering & redundancy to minimize downtime. -Test Performance: Conduct thorough testing to verify the application runs efficiently in a virtual environment. -Backup & Disaster Recovery: Implement regular backup & a solid disaster recovery plan. -Monitor Continuously: Use monitoring tools for performance tracking & proactive issue resolution.

There are several vendors that provide virtualization services, such as VMware, Nutanix, and Citrix. Each vendor has its own unique features. The IT team of a company that will be managing their infrastructure may have expertise in a specific vendor. While it is a good idea to choose a vendor based on their experienced resources, it is also true that experts can learn new technologies quickly. Therefore, it is best to select the right tools that meet the enterprise requirements and make operations hassle-free.

The costs and benefits also need to be considered together with risks. Sometimes migrating a critical environment could impact for a long time an organization. Some business rules needs more careful during the assessment and how could solve problems if It happens on new environment.

Designing a virtual machine is influenced by various factors such as the software it will run, the number of users accessing its services, and the required networking bandwidth for smooth operations. It is recommended to use a thin-provisioned small-sized virtual disks as it is more convenient and faster to migrate and recover in case of any disaster for the newly created VMs. Also it's best to use hot adds of virtual hardware if it supports and we can test gradually by adding more resources on demand.

When we talk about migration, the main mindset is planning, planning and planning. Even with a long time create planning before migrate, things could be happen on wrong way after migrate. The main point is create a disaster recovery and mitigate plan to critical situations after migration.
