If you’re a Terraform user, you may have heard of Cost Estimation and Clustering for Terraform Enterprise (Cost Estimation is also available for Terraform Cloud). We’re excited to provide both of these capabilities to the Terraform community.

Cost Estimation

Decentralized purchasing model. Anyone
has the ability to spend money for the
company.
Makes it difficult to track down the
source of spend.
The Challenge
Cost
Management

1. Visibility:
- Infrastructure as code as the source of record for
every resource.
- Cost Estimation per workspace from an
infrastructure plan (in Terraform).
2. Insights & Actions:
- Create a set of Sentinel cost policies.
- Enforce Sentinel policies automatically against every
Terraform run.
3. Analytics & Optimizations:
- Analyze costs associated with infrastructure
- Take action to reduce cloud spend
The SolutionUse Case:
Cost Management
with Cost
Estimation

Example
Software company
● Azure testing for custom application
● Contractor departed and left 100 8-core
VMs running that were launched via a
ScaleSet (new feature at the time)
● $72K unnecessarily spent in 2.5 months.

Example
Telecommunication
Company
● AWS customers with massive spend
● Very little insight into complex billing;
where to start with cost optimization
● Large percentage of spend is on IaaS
● Industry estimates that 30-40% of IaaS
wasted.

Performance
& Reliability

18. © 2019 HashiCorp
Example
GM Cruise
● The pace of provisioning varies daily
● Up to 1600+ runs per week
● Runs can take up to an hour
● Option was to manually increase
instance size

19. © 2019 HashiCorp
Example
PricewaterhouseCoopers
(PwC)
● Enterprises have a requirement to
allow instances go down without the
platform going down.
● If it goes down, we don’t provision and
this would impact and stop parts of
their business.

1. Scaling out performance: The
horizontal scaling functionality allows
customers the ability to run very large
numbers of concurrent Terraform runs
within a single installation.
2. Redundant for high availability:
clustering groups multiple nodes
together to withstand a failure within
the cluster.
The SolutionA redundant, horizontally
scalable cluster for
performance and reliability

1. Simple & Repeatable: Terraform installs
Terraform Enterprise with a set of Terraform
modules that take less than 20 minutes to run.
2. Multi-Cloud: There are modules specific to the
environment Terraform Enterprise is being
installed onto (AWS, Azure, GCP, etc.)
3. Customize: Module variable allow for cluster size
and other specification to be customized.
The application can be accessed at the configured
hostname immediately without needing to further
configure it on the dashboard site.

repeatable install
