Application Load Balance features and specs

• Layer 7 Processing
  Application Load Balancer operates at the application layer (Layer 7), allowing it to make routing decisions based on advanced content-based rules, such as the HTTP headers, request URL, and query string.
• Advanced Routing
  ALB supports dynamic host-based and path-based routing, enabling requests to be dispatched to different backend services based on the URL pattern or the host domain, which is particularly useful for microservices architectures.
• WebSocket and HTTP/2 Support
  Supports sticky sessions and WebSocket, allowing for long-lived sessions and bidirectional communication between clients and servers. It also supports HTTP/2, providing improved performance over HTTP/1.1.
• Integrated Security Features
  ALB integrates with AWS WAF (Web Application Firewall) to secure applications and protect against common web exploits. It also supports TLS offloading, simplifying encryption management.
• Monitoring and Logging
  Offers detailed CloudWatch metrics and logs to monitor traffic patterns, latency, and other critical operational details. This helps in proactively troubleshooting and optimizing performance.

Possible disadvantages of Application Load Balance

• Complex Configuration
  Setting up and configuring ALB might be more complex compared to Network Load Balancers or Classic Load Balancers, especially with intricate routing and security rules.
• Higher Costs
  Application Load Balancers can be more expensive due to advanced features and capabilities, particularly when handling high traffic levels, compared to simpler load balancing solutions.
• Limited Protocol Support
  ALB is primarily designed for HTTP/HTTPS traffic and may not be suitable if your application needs to handle TCP/UDP-based protocols directly.
• Performance Overhead
  Operating at Layer 7 can introduce slight latency due to the additional processing required for content-based routing and SSL termination.

Amazon EC2 features and specs

• Scalability
  Amazon EC2 allows you to quickly scale your resources up or down based on demand. This flexibility helps you manage your compute needs efficiently without overcommitting resources.
• Pay-as-you-go pricing
  With Amazon EC2, you only pay for the instances you use. This usage-based pricing model can help reduce costs, especially for businesses with variable compute workloads.
• Wide range of instance types
  EC2 offers a variety of instance types optimized for different use cases, such as compute-intensive or memory-intensive applications, allowing you to choose the most suitable instance for your needs.
• Global availability
  Amazon EC2 is available in multiple regions around the world, enabling you to deploy your applications closer to your users for reduced latency and improved performance.
• Integration with other AWS services
  EC2 integrates seamlessly with other AWS services such as S3, RDS, and VPC, providing a comprehensive cloud infrastructure for your applications.
• Security and compliance
  Amazon EC2 provides a range of security features, including VPC, IAM roles, and encryption, to help you protect your data and comply with regulatory requirements.

Possible disadvantages of Amazon EC2

• Complexity
  Managing EC2 instances can be complex, especially as your infrastructure grows. This may require specialized knowledge and skills to properly configure, monitor, and maintain the instances.
• Cost management
  Although the pay-as-you-go model can be cost-effective, it can also lead to unexpected expenses if resources are not managed carefully. Overprovisioning or forgetting to shut down instances can quickly increase costs.
• Performance variability
  While EC2 offers high performance, there can be variability in resources allocated to your instances, especially in the shared tenancy model. This can lead to occasional performance inconsistencies.
• In-depth knowledge required
  To fully leverage Amazon EC2, a good level of expertise in AWS services, cloud computing concepts, and best practices is required. This can be a barrier for organizations without adequate technical skills.
• Vendor lock-in
  Relying heavily on Amazon EC2 can lead to vendor lock-in, making it challenging to migrate to alternative platforms or cloud providers without significant effort and potential downtime.
• Privacy concerns
  Although AWS provides robust security measures, some organizations may have concerns about storing sensitive data on a third-party managed service and prefer managing their own infrastructure.
