Firecracker vs. FreeNAS

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.

FreeNAS is well suited for most storage serving scenarios, whether it be for an office file server, backup destinations, data replication across the internet, or as backend storage for virtual machines. It can serve various types of clients via a plethora of standard protocols and can easily integrate with existing infrastructure using LDAP authentication and so on. It's pretty simple to use (it helps to have at least a basic understanding of the underlying technologies) and almost maintenance-free. One scenario that springs to mind that it may not be appropriate for (yet) is as S3 storage. However, S3 functionality was added in a recent release and may have improved greatly since then. I'm sure it will eventually work very well for this.

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

• The FreeNAS web interface is modern looking. It makes tasks like provisioning drives into raid volumes easy.
• The ZFS raid option allows you to add in an SSD as a cache drive to increase performance.

• 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.

• Not good for beginners as it requires deep understanding of networking and storage.
• Most of the good and required features are not available in free version.

FreeNAS effectively uses all resources really well and it is highly recommended for in premises NAS. It has unlimited ROI as it is really free and open-source. The only payment we need to pay is when we need any support from those guys. FreeNAS helps us to effectively do our work with the legacy systems as it manages all the components really well. FreeNAS although rebranded to TrueNAS will still be there until our legacy systems run.
