Nomad refers to popularly used for cluster management in production by many small-scale and large-scale organizations, as well as start-ups. Its key features include Simplicity & Reliability, Flexibility, Device Plugins & GPU Support, Federation for Multi-Region, Proven Scalability, and HashiCorp Ecosystem. Nomad works on macOS, Windows, and Linux systems.

Terraform refers to a tool that serves the purpose of building, changing, and versioning infrastructure with safety and efficiency. Terraform has the capacity of managing service providers which are already in existence or popular, as well as custom in-house solutions. Terraform can also manage low-level components. It helps to build new infrastructure from scratch.

Comparison Table Between Nomad and Terraform

What is Nomad?

Nomad refers to popularly used for cluster management in production by many small-scale and large-scale organizations, as well as start-ups. Its key features include Simplicity & Reliability, Flexibility, Device Plugins & GPU Support, Federation for Multi-Region, Proven Scalability, and HashiCorp Ecosystem. Because Nomad is an orchestrator, it has flexibility. This helps organizations to run containers, legacy, and batch applications at the same time on infrastructure. It helps in bringing core orchestration benefits to legacy applications. This can be done without the need for containerization via pluggable task drivers.

Nomad is entirely self-contained as it runs as a single binary. It combines resource management and scheduling into one system without any external services for storage or coordination. It is capable of automatically handling application, node, and driver failures. It is also distributed and resilient. Nomad also offers built-in support for GPU workloads. These include machine learning (ML) and artificial intelligence (AI). For automatic detection and resource utilization from hardware devices, it uses device plugins. These include GPU, FPGAs, and TPUs.

For multi-region federation, native support is provided due to which multiple clusters can be linked together. Nomad possesses the ability to be optimistically concurrent. Which helps in increasing throughput and reducing latency for workloads. Nomad has native integrations with Terraform, Consul, Vault for the purpose of provisioning, service discovery, and secrets management.

What is Terraform? 

Terraform refers to a tool that serves the purpose of building, changing, and versioning infrastructure with safety and efficiency. Terraform has the capacity of managing service providers which are already in existence or popular, as well as custom in-house solutions. The components needed to run a single application are described to Terraform by configuration files. Terraform creates an execution plan in which it states the process of reaching the preferred state. It later executes the same for building the given infrastructure. Terraform has the ability to determine changes and create new plans according to the configuration changes.

Terraform can also manage low-level components. These components include computing instances, storage, and networking, DNS entries, SaaS features, and others. The key features of Terraform comprise Infrastructure as Code, Execution Plans, Resource Graph, and Change Automation. For describing Infrastructure in terraforming infrastructure, a high-level configuration syntax is utilized. Which helps in getting a blueprint, sharing, and reusing. 

Planning is a step in Terraform In, which creates an execution plan. This plan shows Terraform activities after user calls apply. And lets the user have no surprises with manipulation. Terraform Resource Graph is a graph of a user’s resources and parallelism with creation and modification. In an infrastructure complex, changesets can be applied with less interaction and human errors using Terraform.

Main Differences Between Nomad and Terraform

Conclusion 

HashiCorp was founded in 2012. Over the years, it has turned into the massive company it is today. Since their initial release, they have been consistently providing their customers or users with quality products, applications, and services.
