Terraform features and specs

• Infrastructure as Code
  Terraform allows you to define your infrastructure in configuration files that can be versioned and stored in a version control system. This makes it easy to track changes, roll back if necessary, and collaborate with team members.
• Multi-Cloud Support
  Terraform supports various cloud providers such as AWS, Azure, Google Cloud, and others. This allows you to manage your entire infrastructure using a single tool, regardless of the underlying provider.
• Immutability
  Terraform promotes immutable infrastructure, meaning once a component is created, it is not modified in place but replaced if changes are needed. This leads to more predictable and stable deployments.
• State Management
  Terraform maintains the state of your infrastructure, which helps in tracking resource changes over time and making incremental updates. This is crucial for applying changes in a controlled manner.
• Community and Ecosystem
  Terraform has a large and active community, along with a rich ecosystem of providers and modules. This makes it easier to find support, share solutions, and leverage pre-built components.

Possible disadvantages of Terraform

• Complex State Management
  While state management is a significant feature, managing state files can become complex and risky. Issues like state file corruption or sharing between team members can lead to challenges.
• Learning Curve
  Terraform has a steep learning curve for beginners, especially those who are not familiar with infrastructure as code concepts or the HashiCorp Configuration Language (HCL).
• Partial Updates
  Terraform's plan and apply operations are not atomic, meaning that partial updates can sometimes leave your infrastructure in an inconsistent state if an error occurs during execution.
• Dependency Management
  Managing dependencies between resources can be challenging in Terraform. Misconfigured dependencies can lead to issues during resource creation, deletion, or updates.
• Cost Management
  While Terraform is excellent for provisioning resources, it does not have built-in cost management or optimization features. Users need to rely on third-party tools to manage and optimize costs.

DynamoDB features and specs

• Scalability
  DynamoDB automatically scales up and down to handle your application's needs, with no intervention required. This allows for easy handling of traffic spikes and growth over time.
• Performance
  With its fast, predictable performance at any scale, DynamoDB ensures low-latency responses, even with large volumes of data.
• Fully Managed
  As a fully managed service, DynamoDB handles hardware provisioning, setup, configuration, replication, software patching, and backups, letting you focus on your application.
• Flexible Data Model
  DynamoDB supports both document and key-value store models, providing flexibility in how you structure your data.
• Security
  DynamoDB integrates with AWS Identity and Access Management (IAM) to provide fine-grained access control and encrypts data at rest and in transit.
• Global Tables
  You can create multi-region, fully replicated tables for high availability and globally distributed apps with low latency reads and writes.
• Event-Driven Architecture
  DynamoDB integrates with AWS Lambda for automatic triggering and the creation of event-driven architectures.

Possible disadvantages of DynamoDB

• Pricing Complexity
  DynamoDB's pricing model, which charges based on read and write capacity units, storage, and data transfer, can be complex and difficult to predict.
• Limited Query Capabilities
  DynamoDB does not support complex queries as well as traditional SQL databases. Querying capabilities are limited primarily to primary key attributes.
• Secondary Indexes
  While DynamoDB supports secondary indexes, their use can be limited and complex to manage effectively compared to relational databases.
• Consistency
  DynamoDB offers eventual consistency by default. While strongly consistent reads are available, they can be more expensive and slower.
• Data Size Limitations
  Each item in a DynamoDB table must be 400KB or less, limiting the amount of data you can store in a single item.
• Vendor Lock-In
  Using DynamoDB heavily ties your application to AWS, which can be a downside if you want to maintain flexibility in your cloud infrastructure choices.
