Web and application hosting involve providing a platform for websites and applications to be accessible over the internet.

This typically involves storing the website or application files on a server and configuring the server to handle incoming requests from users’ browsers or devices.

Application hosting often involves more complex configurations, & should be scalable, reliable, and secure. These features can be crucial for hosting applications with varying loads and requirements.

It is an execution model where the cloud provider dynamically manages the allocation and provisioning of servers while you can focus on writing code and deploying it in the form of functions, which are small, single-purpose pieces of code that respond to events.

Key aspects of serverless computing include:

• No server management
• Event-driven
• Pay-per-use pricing
• Scalability

Storage and backup are essential components of modern IT infrastructure, ensuring data availability, integrity, and resilience against data loss or corruption. Storage types, backup strategies and methods varies as per needs and availability of technologies.

It is essential considering

• Disaster recovery
• Compliance & legal requirements
• To manage data lifecycle

Security and compliance are crucial aspects of any IT infrastructure, ensuring that systems, data, and operations are protected against unauthorized access, breaches, and compliance violations.

Networking and content delivery are fundamental aspects of modern IT infrastructure, enabling efficient communication, data transfer, and content distribution. Content Delivery Networks (CDNs) distribute content across multiple servers located in different geographic locations, reducing latency and improving performance for users.

Network fundamentals take care of

• DNS
• VPN
• Subnetting & Routing
• Firewalls
• Intrusion Detection and Prevention Systems (IDPS)

DevOps and Application Lifecycle Management (ALM) are methodologies and practices that focus on improving collaboration, communication, and integration between development and operations teams throughout the application development lifecycle. DevOps and ALM are complementary approaches that aim to improve the software development process.

Some key Principles followed are :

• Automation
• Continuous Integration
• Continuous Delivery
• Continuous Monitoring

Despite having such great services cultural & legacy application challenges remain.

Remote Desktop refers to the ability to access and control a computer or virtual machine from a remote location.

It enables users to access their desktop environments from anywhere, using any device with an internet connection and it takes care of security measures such as encryption, authentication, and access controls are typically implemented to protect data and ensure secure remote access.

Application Streaming is a technology that allows applications to be delivered and executed on client devices without the need for installation.

It delivers only the necessary components of an application to the client device, reducing the need for large downloads or installations improving application performance, reduce resource usage on client devices, and simplify application management and deployment.

AWS Disaster Recovery involves implementing strategies and solutions to ensure the availability and resilience of applications and data in the event of a disaster.

This typically includes leveraging AWS services to create backup environments, replicate data, and establish failover mechanisms that can quickly restore operations after an outage or failure.

Effective disaster recovery solutions on AWS should be cost-effective, automated, and tailored to meet specific recovery time objectives (RTO) and recovery point objectives (RPO). These features are essential for minimizing downtime and ensuring business continuity in the face of unexpected disruptions.
