Domain 1: Cloud Concepts Flashcards
Security
AWS offers a robust and secure infrastructure with multiple layers of protection, including encryption, access controls, and compliance certifications, ensuring data and application security.
Reliability
AWS provides high availability and durability by replicating data across multiple data centers and using fault-tolerant infrastructure to minimize downtime.
High-Availability
AWS ensures that applications and services remain available even during system failures, distributing traffic across multiple servers and regions.
Elasticity
AWS allows resources to automatically scale up or down based on demand, ensuring optimal performance and cost efficiency.
Agility
AWS enables quick deployment of resources, easy experimentation, and rapid scalability, empowering businesses to respond faster to market changes.
Pay-as-you-go Pricing
AWS offers a flexible payment model where users pay only for the resources they use, avoiding upfront costs and enabling cost optimization.
Scalability
AWS provides the ability to scale resources quickly, allowing applications to handle varying workloads and accommodate growth.
Global Reach
AWS operates in multiple geographic regions worldwide, enabling businesses to reach a global audience and reducing latency for end-users.
Economies of Scale
Due to its large customer base, AWS can offer cost-effective services and resources, passing on the benefits of economies of scale to its users.
Overall Value Proposition
Shifting technical resources to revenue-generating activities: By offloading infrastructure management to AWS, businesses can free up their IT teams to focus on developing innovative solutions and delivering value to customers rather than dealing with hardware and maintenance tasks.
Operation Expenses (OpEx)
These are ongoing expenses related to running and managing services on the AWS Cloud, such as subscription costs, data transfer fees, and support charges.
Capital Expenses (CapEx)
These are upfront costs for purchasing physical hardware, which is not a significant factor in the AWS Cloud since AWS provides the underlying infrastructure.
On-Prem Labor Costs
This includes salaries and benefits for IT personnel managing on-premises infrastructure, which can be reduced or repurposed when using AWS services.
Software Licensing Costs (Cloud Migration)
Some software licenses may be more cost-effective when running on AWS, while others may require specific arrangements or incur additional charges.
Right-Size Infrastructure
AWS allows businesses to adjust resources to match actual demand, avoiding over-provisioning and wastage.
Benefits of Automation
AWS provides various automation tools that reduce manual tasks, increase efficiency, and minimize human errors, leading to cost savings.
Reduce Compliance Scope
AWS compliance programs can help businesses meet regulatory requirements efficiently, potentially reducing compliance-related costs.
Managed Services
Using AWS managed services like Amazon RDS, Amazon ECS, Amazon EKS, and Amazon DynamoDB can lower operational overhead and reduce the need for dedicated expertise in managing these services.
Design for Failure
In cloud architecture, applications are designed to handle failures gracefully rather than trying to prevent every possible failure. This involves using redundancy, automated backups, and distributed components to ensure system availability and resilience in the face of failures.
Decouple Components versus Monolithic Architecture:
Cloud architecture encourages breaking down applications into smaller, loosely coupled components. This allows for independent development, deployment, and scalability of each component, leading to increased flexibility and easier maintenance.
Implement Elasticity
Elasticity refers to the ability to automatically scale resources up or down based on demand. Cloud architecture should be designed to take advantage of this elasticity, ensuring that applications can handle varying workloads efficiently and cost-effectively.
AWS Management Console
A web-based interface that allows users to manage AWS resources using a graphical user interface (GUI). It is suitable for managing individual resources and performing basic tasks.
AWS Command Line Interface (CLI)
A command-line tool that enables users to interact with AWS services and resources using text commands. It offers scripting capabilities and is useful for automating tasks and managing resources in bulk.
AWS Software Development Kits (SDKs)
SDKs provide libraries and APIs for various programming languages, allowing developers to integrate AWS services into their applications and manage resources programmatically.
