Daily orchestration of complex ai workflows has boosted my research and automation capabilities
Orchestration primarily decides which agent handles which part of a task and manages errors, retries, and complete state while maintaining the workflow effectively. On the orchestration side, branching, looping, and human approvals support non-linear workflows in production environments with real-time access. Through refined and improved prompts, this helps in closing the loop with actual users. One unique feature that stood out is that every step in the workflow can pause or recover from failures. Instead of finishing the entire agent in one go, this approach is interesting because if there is a minor change in a previously completed step regarding the state, I can re-edit and restart from the beginning. This is truly impressive.

Automation of cloud infrastructure has transformed how our team manages Terraform workflows
Spacelift has other features beyond Terraform, including Ansible, Pulumi, Terragrunt, and it also helps with Kubernetes, although we haven't used it for the other tools. We have only used it for Terraform Infrastructure as Code, and it has helped us significantly. One standout feature compared to Terraform Cloud is the ability to apply policies. For example, we want to restrict engineers in our team from building servers with a particular SKU, such as in Azure, where we do not want to run servers with a SKU higher than the standard D4sv5. We can apply those policies in Spacelift, and the RBAC and access policies features are really excellent in Spacelift, which we do not find in any of the other competitor tools. The pricing is also competitive compared to Terraform Cloud. The access policy features allow us to assign specific policies since we have three environments in our company: Dev, QA, and Prod. We assign policies so that anyone can run code from Dev and QA servers, but we assign a policy for specific people, such as managers, to run code in Prod. This is a very good feature from Spacelift that we have implemented for the access policy. Spacelift has positively impacted our organization as a CI/CD tool for application deployment and development. Although we use other CI/CD tools like Azure DevOps and GitHub Actions, there wasn't a specific tool for Terraform Infrastructure as Code until Spacelift came along. It allows us to easily configure our servers and build a number of them on our cloud. While other CI/CD tools have started to include configuration features, Spacelift offers many other benefits that make it an excellent tool to use.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I have used many solutions, but Glean Platform is the best, and I would truly appreciate it if everyone considers this platform."
"When I searched for internal information spread across different systems, Glean Platform did centralize and retrieve that data for me effectively, giving me eighty percent accuracy."
"Life became so easy when we started using Glean Platform."
"Glean Platform offers excellent user interface design and integration capabilities with other platforms."
"Glean Platform has positively impacted my organization by speeding up a lot of repetitive tasks and making it easier for people outside of support to understand what kind of issues impact the support groups."
"Glean Platform has increased productivity by at least one hundred hours per week for my organization."
"The best features Glean Platform offers include the ability to create my own agents, for example, I created a self-service agent for my stakeholders, so rather than email me, I sent them a link to an agent where the agent asks them questions and drills down to exactly what they need, and then I get a qualified response from them."
"Glean Platform has positively impacted our organization, especially in terms of productivity for both us and our customers."
"The metrics show that fewer employees are needed, money is saved based on past experiences with different cloud management or Infrastructure as Code management tools, and efficiency has improved significantly in terms of Infrastructure as Code deployment."
"Spacelift has positively impacted my organization by making it very easy to manage the different modules with a very clear interface."
"Knowing the HashiCorp Configuration Language (HCL) makes it easier to use without issues."
"After using Spacelift, I noticed a 90% reduction in time saved for repetitive infrastructure tasks, as the cloud configuration speed has doubled."
"A valuable feature of Spacelift is that you can attach labels, and it is a modernized tool for infrastructure deployments. It is pull request-based, and you can see all the Terraform plan and apply logs on the pull request itself, which is not available across any other CI/CD tools."
"I appreciate that I just have to connect to my AWS account with my credentials, and Spacelift handles the rest."
"Spacelift has positively impacted my organization in significant ways in terms of building infrastructure as code."
"Spacelift has positively impacted my organization by reducing manpower, as it reduced the efforts of resources in the team, where previously a job done by two or three engineers can now be easily managed by one engineer using Spacelift."
 

Cons

"My experience with pricing, setup cost, and licensing for Glean Platform reveals limited options, and I wish there was more customization available."
"I chose seven out of ten because if I could upload PDFs and have them analyzed, or have it integrate with my Gmail and help me go through my emails, that would be very useful, but I do not think it does that."
"Currently, Glean Platform does not integrate with Teams, Microsoft-owned platforms."
"Glean Platform can implement more models. The NLP creation could be a little faster, and while debugging is amazing, the routing also needs to provide higher quality outputs sometimes rather than extensive searching."
"Also, the latency that the platform offers is a little high right now; what I have noticed is that on a particular query, the user has to wait a long time in order to get responses."
"My experience with pricing, setup cost, and licensing is that the licenses were expensive, and it was hard to convince the company to adopt based on that."
"In workflow agents, I would prefer that we do not use AI in every step and instead we have a toggle button or something which can configure whether AI should be used in this specific search field or not, or in this specific node or not, because currently it's using AI in all nodes which sometimes messes up the output."
"Sometimes Glean Platform gets slowed down."
"Pricing could be a little lower to make it a very robust tool, and it can improve areas in scalability and integrate some open-source tools."
"Spacelift currently lacks features that can help with complex type deployments and coordination for major deployments."
"In the free version, there's no straightforward way to be notified once a deployment is finished."
"Synchronization can be difficult when using older and newer versions with Kubernetes and HashiCorp."
"I think an improvement for Spacelift would be a feature to run multiple stacks."
"I chose a rating of six out of ten because I think multiple other tools similar to Spacelift exist, for example, many automation tools such as Jenkins or other cloud-native tools that perform efficiently compared to Spacelift."
"If I had to think of one area where Spacelift could improve, it would be the graph where we orchestrate, as the graph looks very complicated and complex, so perhaps it could be simplified."
"Perhaps the learning curve could be a bit steep if someone is completely new to Spacelift and only has experience with plain Terraform."
