SQLite features and specs

• Zero Configuration
  SQLite does not require any server setup or configuration, allowing for easy integration and deployment in applications.
• Lightweight
  It is extremely lightweight, with a small footprint, making it ideal for embedded systems and mobile applications.
• Self-Contained
  SQLite is self-contained, meaning it has minimal external dependencies, which simplifies its distribution and usage.
• File-Based Storage
  Data is stored in a single file, which makes it easy to manage and transfer databases as simple files.
• ACID Compliance
  SQLite supports Atomicity, Consistency, Isolation, and Durability (ACID) properties, ensuring reliable transactions.
• Cross-Platform
  SQLite is available on numerous platforms, including Windows, MacOS, Linux, iOS, and Android, providing a broad compatibility range.
• Public Domain
  SQLite operates under the public domain, allowing for unrestricted use in commercial and non-commercial applications.

Possible disadvantages of SQLite

• Limited Scalability
  SQLite is not designed to handle high levels of concurrency and large-scale databases, making it less suitable for large, high-traffic applications.
• Write Performance
  Write operations can be slower compared to server-based databases, especially under heavy write loads.
• Lack of Certain Features
  SQLite lacks some advanced features offered by other RDBMS like stored procedures, user-defined functions, and full-text search indexing.
• Security
  As SQLite is file-based, it might lack some of the security features present in server-based databases, such as sophisticated access control.
• Concurrency
  SQLite uses a locking mechanism to control access to the database, which can lead to contention and performance bottlenecks in highly concurrent environments.
• Backup and Restore
  While it's straightforward to copy SQLite database files, it lacks the advanced backup and restore features found in more complex RDBMS.

Amazon ElastiCache features and specs

• Scalability
  Amazon ElastiCache allows for seamless scaling of your cache cluster. You can easily add or remove nodes to adjust to the workload demands, ensuring efficient resource management.
• Managed Service
  ElastiCache is fully managed by AWS, meaning that infrastructure tasks such as hardware provisioning, patching, and maintenance are handled by Amazon, reducing operational overhead for users.
• High Performance
  Designed for delivering low latency and high throughput, ElastiCache can significantly improve the performance of applications by reducing the time to retrieve data from databases.
• Compatibility
  It supports popular caching engines such as Redis and Memcached, allowing users to work with familiar technologies and migrate existing setups to the AWS environment with ease.
• Security and Compliance
  ElastiCache provides robust security features including VPC integration, data encryption, and IAM policies, helping to ensure compliance with various industry standards.

Possible disadvantages of Amazon ElastiCache

• Cost
  As a premium managed service, ElastiCache can become expensive, especially for large-scale deployments or when utilizing advanced features, which may not be ideal for all budget constraints.
• Limited Customization
  Because it is a managed service, there are limits to the customization of infrastructure and configurations when compared to self-managed solutions, which might not accommodate all specific needs.
• Dependency on AWS Ecosystem
  Using ElastiCache ties your infrastructure to AWS, which might not be suitable for organizations seeking a multi-cloud strategy or those who wish to avoid vendor lock-in.
• Learning Curve
  New users may face a learning curve, especially if they are not already familiar with AWS services and console navigation, potentially requiring additional training or support.
• Regional Limitations
  Not all features may be available in every AWS region, which could impact global deployments and necessitate strategic planning for distribution and redundancy.
