Reduce costs, improve performance, improve security Show
AWS Trusted Advisor provides recommendations that help you follow AWS best practices. Trusted Advisor evaluates your account by using checks. These checks identify ways to optimize your AWS infrastructure, improve security and performance, reduce costs, and monitor service quotas. You can then
follow the recommendations to optimize your services and resources. AWS Basic Support and AWS Developer Support customers can access core security checks and checks for service quotas. AWS Business Support and AWS Enterprise Support customers can access all checks, including cost optimization, security, fault tolerance, performance, and service quotas. For a complete list of checks and descriptions, see the Trusted Advisor Best Practices. AWS Trusted Advisor Priority helps
you focus on the most important recommendations to optimize your cloud deployments, improve resilience, and address security gaps. Available to AWS Enterprise Support customers, Trusted Advisor Priority provides prioritized and context-driven recommendations that come from your AWS account team as well as machine-generated checks from AWS services. How to start using AWS Trusted Advisor (11:45) BenefitsChecks from Trusted Advisor analyze your AWS environment and recommend actions to follow best practices. Cost optimizationTrusted Advisor can help you save cost with actionable recommendations by analyzing usage, configuration and spend. Examples include identifying idle RDS DB instances, underutilized EBS volumes, unassociated Elastic IP addresses, and excessive timeouts in Lambda functions. PerformanceTrusted Advisor can help improve the performance of your services with actionable recommendations by analyzing usage and configuration. Examples include analyzing EBS throughput and latency, compute usage of EC2 instances, and configurations on CloudFront. SecurityTrusted Advisor can help improve the security of your AWS environment by suggesting foundational security best practices curated by security experts.
Examples include identifying RDS security group access risk, exposed access keys, and unnecessary S3 bucket permissions. Fault toleranceTrusted Advisor can help improve the reliability of your services. Examples include examining Auto scaling EC2 groups, deleted health checks on Route 53, disabled Availability Zones, and disabled RDS backups. Service quotasService quotas are the
maximum number of resources that you can create in an AWS account. AWS implements quotas to provide highly available and reliable service to all customers, and protects you from unintentional spend. Trusted Advisor will notify you once you reach more than 80% of a service quota. You can then follow recommendations to delete resources or request a quota increase. How it works AWS support for Internet Explorer ends on 07/31/2022. Supported browsers are Chrome, Firefox, Edge, and Safari. Learn more » What defines a modern data center?Modern data centers are very different than they were just a short time ago. Infrastructure has shifted from traditional on-premises physical servers to virtual networks that support applications and workloads across pools of physical infrastructure and into a multicloud environment. In this era, data exists and is connected across multiple data centers, the edge, and public and private clouds. The data center must be able to communicate across these multiple sites, both on-premises and in the cloud. Even the public cloud is a collection of data centers. When applications are hosted in the cloud, they are using data center resources from the cloud provider. Why are data centers important to business?In the world of enterprise IT, data centers are designed to support business applications and activities that include:
What are the core components of a data center?Data center design includes routers, switches, firewalls, storage systems, servers, and application delivery controllers. Because these components store and manage business-critical data and applications, data center security is critical in data center design. Together, they provide: Network infrastructure. This connects servers (physical and virtualized), data center services, storage, and external connectivity to end-user locations. Storage infrastructure. Data is the fuel of the modern data center. Storage systems are used to hold this valuable commodity. Computing resources. Applications are the engines of a data center. These servers provide the processing, memory, local storage, and network connectivity that drive applications. How do data centers operate?Data center services are typically deployed to protect the performance and integrity of the core data center components. Network security appliances. These include firewall and intrusion protection to safeguard the data center. Application delivery assurance. To maintain application performance, these mechanisms provide application resiliency and availability via automatic failover and load balancing. What is in a data center facility?Data center components require significant infrastructure to support the center's hardware and software. These include power subsystems, uninterruptible power supplies (UPS), ventilation, cooling systems, fire suppression, backup generators, and connections to external networks. What are the standards for data center infrastructure?The most widely adopted standard for data center design and data center infrastructure is ANSI/TIA-942. It includes standards for ANSI/TIA-942-ready certification, which ensures compliance with one of four categories of data center tiers rated for levels of redundancy and fault tolerance. Tier 1: Basic site infrastructure. A Tier 1 data center offers limited protection against physical events. It has single-capacity components and a single, nonredundant distribution path. Tier 2: Redundant-capacity component site infrastructure. This data center offers improved protection against physical events. It has redundant-capacity components and a single, nonredundant distribution path. Tier 3: Concurrently maintainable site infrastructure. This data center protects against virtually all physical events, providing redundant-capacity components and multiple independent distribution paths. Each component can be removed or replaced without disrupting services to end users. Tier 4: Fault-tolerant site infrastructure. This data center provides the highest levels of fault tolerance and redundancy. Redundant-capacity components and multiple independent distribution paths enable concurrent maintainability and one fault anywhere in the installation without causing downtime. Which of the following statement best explains the ability of the network to provide fault tolerance?Which of the following statements best explains the ability of the network to provide fault tolerance? A The network is considered fault-tolerant because there are redundant paths between each pair of devices.
What feature's of the Internet makes it faultA big contributor to the fault tolerance of the Internet is the redundancy in network routing paths.
How does that increase the fault tolerance of routing on the Internet Choose 1 answer?How does that increase the fault tolerance of routing on the Internet? A. Each router can pick a connection that's closest to the destination.
Which of the following is the best description of how routing works on the Internet?Which of the following is the best description of how routing works on the Internet? A computer stores the destination IP address in the IP packet header and sends the packet to the nearest router.
