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.

    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.

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.
