Firecracker vs. Oracle Solaris

While deploying workloads in lightweight microVMs presents a couple of perks, Firecracker may not be the best software to handle this. Startup times are slow and scalability is quite limited because of the jailer and virtualization barriers. We have had security breaches on isolated EC2 instances while using Firecracker. It however has a silver lining by improving how serverless functions in container ecosystems are run with their VMMs.

It's good for environments that need to operate 24/7 due to its stability, as I mentioned before. It's also very good for enterprise applications that can't afford unscheduled downtime, for truly high-priority environments. I don't think it would be recommended for small companies with people who have no prior knowledge of the tool, as the learning curve is quite steep.

• It makes it easy to secure virtual machines as they are segmented into microvms with a minimal attack surface area

• Excludes devices unnecessarily
• Has a slow startup time the basis being to improve security which is quite irrelevant.
• It has limited functionalities on monitoring VMs despite being an open source.

• It seems that Solaris is becoming an afterthought at Oracle.
• Oracle should be more vocal in their commitment to Solaris
• Support Costs

You need to take the time to learn it. It is a massive product.

The support teams are well trained and responsive. Patches are rolled out regularly and are easy to deploy and backout.

Stress testing and timing is key. You need test systems that mirror the live environments. User testing must be reflected in peak loads.

We used Windows Server quite a bit because of the ease of use for the team, file sharing, Active Directory, and systems integrated with Windows; learning was easier, and the interface was more user-friendly. On the other hand, Oracle stood out for its stability because we provide services that keep environments up and running 24/7.
