Eureka vs Terraform: What are the differences?

Scalability: Eureka is a service registration and discovery tool, while Terraform is an infrastructure provisioning tool. Eureka focuses on dynamic scaling by allowing services to discover and register with each other, resulting in a highly scalable and resilient system. On the other hand, Terraform enables the provisioning and management of infrastructure resources, such as virtual machines and networks, in a scalable manner.
Scope: Eureka is primarily designed for microservices architecture, providing service registration and discovery capabilities for distributed systems. In contrast, Terraform has a broader scope and can be used to provision and manage infrastructure resources on various cloud providers, including AWS, Azure, and Google Cloud.
Language: Eureka is written in Java and therefore best suited for Java-based applications. Terraform, on the other hand, uses a declarative language called HashiCorp Configuration Language (HCL) that is not tied to a specific programming language, making it more accessible and flexible for a wider range of users.
Abstraction Level: Eureka operates at a higher abstraction level, providing a simplified interface for service registration and discovery. It abstracts away the complexity of managing services in a distributed system. In contrast, Terraform allows users to define infrastructure as code, giving them finer control and granularity over the provisioning and configuration of resources.
Integration: Eureka integrates seamlessly with Spring Cloud, a popular framework for building microservices in Java. It provides native support for Eureka, making it easy to incorporate service discovery into Spring-based applications. Terraform, on the other hand, integrates with various cloud provider APIs and offers a wide range of provider plugins, enabling users to manage resources across different cloud platforms.
Maturity: Eureka has been around for a longer time and is well-established as a service registry and discovery solution. It has a large user base and extensive community support. Terraform, on the other hand, has gained significant popularity in recent years and is continuously evolving with new features and improvements being introduced regularly.

In Summary, Eureka and Terraform differ in terms of their focus on service registration and discovery vs. infrastructure provisioning, their scope, language, abstraction level, integration options, and maturity.

Advice on Terraform, Eureka

Sung Won

Google Cloud IoT Core

Terraform

Python

Context: I wanted to create an end to end IoT data pipeline simulation in Google Cloud IoT Core and other GCP services. I never touched Terraform meaningfully until working on this project, and it's one of the best explorations in my development career. The documentation and syntax is incredibly human-readable and friendly. I'm used to building infrastructure through the google apis via Python , but I'm so glad past Sung did not make that decision. I was tempted to use Google Cloud Deployment Manager, but the templates were a bit convoluted by first impression. I'm glad past Sung did not make this decision either.

Solution: Leveraging Google Cloud Build Google Cloud Run Google Cloud Bigtable Google BigQuery Google Cloud Storage Google Compute Engine along with some other fun tools, I can deploy over 40 GCP resources using Terraform!

I personally am not a huge fan of vendor lock in for multiple reasons:

I've seen cost saving moves to the cloud end up costing a fortune and trapping companies due to over utilization of cloud specific features.
I've seen S3 failures nearly take down half the internet.
I've seen companies get stuck in the cloud because they aren't built cloud agnostic.

I choose to use terraform for my cloud provisioning for these reasons:

It's cloud agnostic so I can use it no matter where I am.
It isn't difficult to use and uses a relatively easy to read language.
It tests infrastructure before running it, and enables me to see and keep changes up to date.
It runs from the same CLI I do most of my CM work from.

Because Pulumi uses real programming languages, you can actually write abstractions for your infrastructure code, which is incredibly empowering. You still 'describe' your desired state, but by having a programming language at your fingers, you can factor out patterns, and package it up for easier consumption.

Detailed Comparison

Terraform	Eureka
With Terraform, you describe your complete infrastructure as code, even as it spans multiple service providers. Your servers may come from AWS, your DNS may come from CloudFlare, and your database may come from Heroku. Terraform will build all these resources across all these providers in parallel.	Eureka is a REST (Representational State Transfer) based service that is primarily used in the AWS cloud for locating services for the purpose of load balancing and failover of middle-tier servers.
Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.;Execution Plans: Terraform has a "planning" step where it generates an execution plan. The execution plan shows what Terraform will do when you call apply. This lets you avoid any surprises when Terraform manipulates infrastructure.;Resource Graph: Terraform builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, Terraform builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.;Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what Terraform will change and in what order, avoiding many possible human errors	-

What are some alternatives to Terraform, Eureka?

Ansible

Ansible is an IT automation tool. It can configure systems, deploy software, and orchestrate more advanced IT tasks such as continuous deployments or zero downtime rolling updates. Ansible’s goals are foremost those of simplicity and maximum ease of use.

Chef

Chef enables you to manage and scale cloud infrastructure with no downtime or interruptions. Freely move applications and configurations from one cloud to another. Chef is integrated with all major cloud providers including Amazon EC2, VMWare, IBM Smartcloud, Rackspace, OpenStack, Windows Azure, HP Cloud, Google Compute Engine, Joyent Cloud and others.

Capistrano

Capistrano is a remote server automation tool. It supports the scripting and execution of arbitrary tasks, and includes a set of sane-default deployment workflows.

Puppet Labs

Puppet is an automated administrative engine for your Linux, Unix, and Windows systems and performs administrative tasks (such as adding users, installing packages, and updating server configurations) based on a centralized specification.

Consul

Consul is a tool for service discovery and configuration. Consul is distributed, highly available, and extremely scalable.

Salt

Salt is a new approach to infrastructure management. Easy enough to get running in minutes, scalable enough to manage tens of thousands of servers, and fast enough to communicate with them in seconds. Salt delivers a dynamic communication bus for infrastructures that can be used for orchestration, remote execution, configuration management and much more.

Fabric

Fabric is a Python (2.5-2.7) library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks.

AWS OpsWorks

Start from templates for common technologies like Ruby, Node.JS, PHP, and Java, or build your own using Chef recipes to install software packages and perform any task that you can script. AWS OpsWorks can scale your application using automatic load-based or time-based scaling and maintain the health of your application by detecting failed instances and replacing them. You have full control of deployments and automation of each component

Zookeeper

A centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. All of these kinds of services are used in some form or another by distributed applications.

etcd

etcd is a distributed key value store that provides a reliable way to store data across a cluster of machines. It’s open-source and available on GitHub. etcd gracefully handles master elections during network partitions and will tolerate machine failure, including the master.
