• Learn about public IP addresses, private IP addresses, and their use cases. (Read more)

Routing and Switching

• Gain knowledge of routing protocols such as Border Gateway Protocol (BGP) and Open Shortest Path First (OSPF). (Explore more)

• Understand VLANs, trunking, and switching concepts. (Discover more)

Network Security

• Learn about firewall technologies, including access control lists (ACLs) and stateful packet inspection. (Find out more)

• Understand Virtual Private Networks (VPNs) and their role in securing network connections. (Learn about VPNs)

• Familiarize yourself with Network Address Translation (NAT) and its different types. (Read about NAT)

DNS and Load Balancing

• Understand the Domain Name System (DNS) and its role in translating domain names into IP addresses. (Learn DNS basics)

• Learn about different types of DNS records, such as A, CNAME, and MX records. (Explore DNS records)

• Explore load balancing concepts, including round-robin, session persistence, and health checks. (Get started with load balancing)

Security Principles

Security is a critical aspect of cloud architecture. Develop a strong understanding of the following security principles:

Identity and Access Management (IAM)

• Master AWS IAM and its role in managing user access to AWS resources. (AWS IAM documentation)

• Learn about IAM policies, roles, and groups. (Understand IAM)

• Understand multi-factor authentication (MFA) and its importance in securing AWS accounts. (Explore MFA)

Encryption and Key Management

• Gain knowledge of encryption algorithms, such as Advanced Encryption Standard (AES) and RSA. (Learn about encryption algorithms)

• Understand the concept of encryption at rest and in transit. (Discover encryption at rest and in transit)

• Familiarize yourself with AWS Key Management Service (KMS) and its role in managing encryption keys. (AWS KMS documentation)

Network Security

• Learn about network security groups, firewalls, and access control lists (ACLs) in AWS. (AWS Network Security)

• Understand the shared responsibility model and how it applies to AWS security. (Read about shared responsibility)

• Familiarize yourself with AWS Web Application Firewall (WAF) and its role in protecting web applications. (AWS WAF documentation)

Storage Technologies

Storage is a critical component of any cloud infrastructure. Gain knowledge of the following storage technologies:

Object Storage

• Learn about Amazon Simple Storage Service (S3) and its features, such as versioning, lifecycle management, and cross-region replication. (AWS S3 documentation)

• Understand the concept of durability and availability in object storage. (Explore S3 durability)

• Familiarize yourself with Amazon Glacier for long-term archival storage. (AWS Glacier documentation)

Block Storage

• Learn about Amazon Elastic Block Store (EBS) and its role in providing persistent block-level storage for EC2 instances. (AWS EBS documentation)

• Understand different EBS volume types, such as General Purpose SSD (gp2), Provisioned IOPS SSD (io1), and Throughput Optimized HDD (st1). (Explore EBS volume types)

File Storage

• Gain knowledge of Amazon Elastic File System (EFS) and its role in providing scalable, fully managed file storage for EC2 instances. (AWS EFS documentation)

• Understand file system features like POSIX compatibility, encryption, and lifecycle management. (Learn about EFS features)

By mastering these essential IT knowledge areas, you'll be well-equipped to tackle the AWS Certified Solutions Architect - Associate (SAA-C03) exam. Remember to leverage the free resources and documentation provided to deepen your understanding of these concepts.
