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.

PM2 features and specs

  • Process Management
    PM2 provides efficient process management, allowing you to easily start, stop, and restart applications. It handles the daemonization of processes and ensures that all your services run continuously.
  • Monitoring & Logging
    PM2 offers robust monitoring and logging features, providing real-time metrics on CPU and memory usage, along with comprehensive logging to help debug issues and monitor application performance.
  • Cluster Mode
    PM2 supports cluster mode, enabling you to run multiple instances of your application to utilize multi-core systems effectively, thereby improving performance and handling more traffic.
  • Easy Deployment
    With PM2, deployment is simplified through built-in functionalities like management of environment variables and automatic startup scripts, making it easier to deploy applications across environments.
  • Platform Agnostic
    PM2 is platform-agnostic and can be used with diverse environments and languages, though it is optimized for Node.js applications, offering flexibility to manage various types of applications.

Possible disadvantages of PM2

  • Overhead
    While PM2 is lightweight, it can add some overhead, particularly in smaller or simpler applications where its full range of features may not be necessary.
  • Configuration Complexity
    For new users or simple applications, PM2's configuration options may seem complex, with a steep learning curve to understand and leverage all available features effectively.
  • Memory Usage
    PM2's memory usage can be higher compared to more minimal solutions, which might be a concern for resource-constrained environments or small-scale projects.
  • Limited to JavaScript by Default
    Although you can manage other types of applications, PM2 is primarily designed for Node.js, so managing non-JavaScript applications could require additional effort or wrappers.
  • Potential Issues with Large Projects
    In some cases, PM2 may face challenges scaling very large projects due to its process management design, requiring more thorough testing and configuration tuning.
