2. Terraform
● Open-source infrastructure as code software tool that provides a
consistent CLI workflow to manage hundreds of cloud services
● Codifies cloud APIs into declarative configuration file to manage the
full lifecycle
○ create new resources, manage existing ones, and destroy those
no longer needed
● HashiCorp Configuration Language (HCL) allows for concise
descriptions of resources using blocks, arguments, and expressions.
● Can manage low-level components like compute, storage, and
networking resources, as well as high-level components like DNS
entries and SaaS features.
● Keeps track of your real infrastructure in a state file, which acts as a
source of truth for your environment
○ uses the state file to determine the changes to make to your
infrastructure so that it will match your configuration.

3. Terraform
● Terraform Plan helps to check whether the execution plan for a
configuration matches your expectations before provisioning or
changing infrastructure.
● Installable Modules
○ Automatically download and install community or partner
modules from the registry with terraform init
● Dependency Graphing
○ Easily generate terraform plan, refresh state, and more, with
Terraform config dependency graphing.
● CDK for Terraform (experimental) allows you to define infrastructure
code in TypeScript, Python, Java, C#, and Go, using the 1000+ existing
Terraform providers and HCL Terraform modules.
● Terraform Registry with 1000+ providers

4. DataStax Astra Terraform Provider
● Allows DataStax Astra users to manage their full
database lifecycle for Astra Serverless databases
● Requires a Token
● Currently Astra Streaming (based on Apache Pulsar)
is not supported.

astra
● Examples

5. Demo
● Spin up Gitpod
● Create a new database
● Create a new keyspace in newly created database
● Download a dependency graph
● Destroy newly created keyspace
● Destroy newly created database

6. Strategy: Scalable Fast Data
Architecture: Cassandra, Spark, Kafka
Engineering: Node, Python, JVM,CLR
Operations: Cloud, Container
Rescue: Downtime!! I need help.
