Let's Encrypt features and specs

• Free of Charge
  Let's Encrypt provides SSL/TLS certificates at no cost, making it an economical choice for individuals and businesses.
• Automated Certificate Issuance and Renewal
  The process of obtaining and renewing certificates can be automated using the ACME protocol, reducing manual intervention and administrative overhead.
• Ease of Use
  Let's Encrypt simplifies the process of enabling HTTPS for websites, even for users with limited technical expertise.
• Security
  Let's Encrypt certificates provide strong encryption, improving the security of data transmitted between clients and servers.
• Widely Recognized
  Certificates issued by Let's Encrypt are trusted by all major web browsers and operating systems.
• Promotes Secure Web Practices
  By making SSL/TLS certificates freely available, Let's Encrypt encourages more websites to adopt HTTPS, contributing to a more secure internet.

Possible disadvantages of Let's Encrypt

• Short Duration of Certificates
  Let's Encrypt certificates are valid for only 90 days, requiring more frequent renewals compared to traditional certificate authorities.
• Limited Support Options
  Let's Encrypt relies on community support and documentation, and does not offer dedicated customer support for troubleshooting and assistance.
• No Extended Validation (EV) Certificates
  Let's Encrypt does not issue Extended Validation (EV) certificates, which provide additional verification and a higher level of trust for business websites.
• Potential for Misuse
  Since certificates are issued for free and with minimal validation, there is a risk that cybercriminals might use them for phishing or other malicious activities.
• No Wildcard Certificates for Multi-Level Subdomains
  While Let's Encrypt supports wildcard certificates for single-level subdomains, it doesn't support them for nested subdomains (e.g., *.sub.example.com).
• Reliance on Third-Party Tools for Automation
  Users may need to rely on third-party tools or scripts for automation, which could introduce additional complexity or security risks.

AWS Lambda features and specs

• Scalability
  AWS Lambda automatically scales your application by running your code in response to each trigger. This means no manual intervention is required to handle varying levels of traffic.
• Cost-effectiveness
  You only pay for the compute time you consume. Billing is metered in increments of 100 milliseconds and you are not charged when your code is not running.
• Reduced Operations Overhead
  AWS Lambda abstracts the infrastructure management layer, so there is no need to manage or provision servers. This allows you to focus more on writing code for your applications.
• Flexibility
  Supports multiple programming languages such as Python, Node.js, Ruby, Java, Go, and .NET, which allows you to use the language you are most comfortable with.
• Integration with Other AWS Services
  Seamlessly integrates with many other AWS services such as S3, DynamoDB, RDS, SNS, and more, making it versatile and highly functional.
• Automatic Scaling and Load Balancing
  Handles thousands of concurrent requests without managing the scaling yourself, making it suitable for applications requiring high availability and reliability.

Possible disadvantages of AWS Lambda

• Cold Start Latency
  The first request to a Lambda function after it has been idle for a certain period can take longer to execute. This is referred to as a 'cold start' and can impact performance.
• Resource Limits
  Lambda has defined limits, such as a maximum execution timeout of 15 minutes, memory allocation ranging from 128 MB to 10,240 MB, and temporary storage up to 512 MB.
• Vendor Lock-in
  Using AWS Lambda ties you into the AWS ecosystem, making it difficult to migrate to another cloud provider or an on-premises solution without significant modifications to your application.
• Complexity of Debugging
  Debugging and monitoring distributed, serverless applications can be more complex compared to traditional applications due to the lack of direct access to the underlying infrastructure.
• Cold Start Issues with VPC
  When Lambda functions are configured to access resources within a Virtual Private Cloud (VPC), the cold start latency can be exacerbated due to additional VPC networking overhead.
• Limited Execution Control
  AWS Lambda is designed for stateless, short-running tasks and may not be suitable for long-running processes or tasks requiring complex orchestration.
