What are the roles and responsibilities of SysOps Administrator Associate?
The main responsibility of an AWS Administrator is to configure cloud management services on AWS in the organization. Moreover, the following are some additional and yet significant roles of AWS Certified SysOps Administrator Associate.
Firstly, Managing the complete AWS life cycle, along with security, provisioning, and automation.
Secondly, Administrating and establishing the architecture of multi-tier systems
Thirdly, Performing services such as kernel patching, errata patching, and software upgrades
Fourthly, Effectively monitoring performance degree and its availability
Lastly, Creating backups and managing disaster recovery
What is the use of AWS Well-Architected Framework?
AWS Well-Architected helps cloud architects to build secure, high-performing, resilient, and efficient infrastructure for their applications and workloads. It is based on five pillars — operational excellence, security, reliability, performance efficiency, and cost optimization. AWS Well-Architected provides a consistent approach for customers and partners to evaluate architectures, and implement designs that can scale over time.
What is an Operational Excellence Pillar?
The operational excellence pillar focus on running and monitoring systems to deliver business value, and continually improving processes and procedures. Major topics include automating changes, responding to events, and defining standards to manage daily operations.
What do you understand by Security Pillar?
The security pillar major area of concern is protecting information and systems. Key topics include confidentiality and integrity of data, identifying and managing who can do what with privilege management, protecting systems, and establishing controls to detect security events.
What is a Reliability Pillar?
The reliability pillar focuses on ensuring a workload performs its intended function correctly and consistently when it’s expected to. A resilient workload quickly recovers from failures to meet business and customer demand. Major topics of concern include distributed system design, recovery planning, and how to handle change.
What do you understand by Performance Efficiency Pillar?
The performance efficiency pillar concerned on areas using IT and computing resources efficiently. Key topics include selecting the right resource types and sizes based on workload requirements, monitoring performance, and making informed decisions to maintain efficiency as business needs evolve.
What are Cost Optimization Pillars?
The cost optimization pillar focuses on avoiding unnecessary costs. Key topics include understanding and controlling where money is being spent, selecting the most appropriate and right number of resource types, analyzing spend over time, and scaling to meet business needs without overspending.
What Is Amazon CloudWatch Logs?
Amazon CloudWatch Logs to monitor, store, and access its user’s log files from Amazon Elastic Compute Cloud (Amazon EC2) instances, AWS CloudTrail, Route 53, and other sources. Moreover, it enables you to centralize the logs from all of your systems, applications, and AWS services that you use, in a single, highly scalable service. One can use logs to see all of your logs, regardless of their source, as a single and consistent flow of events ordered by time, and you can query them and sort them based on other dimensions, group them by specific fields, create custom computations with a powerful query language, and visualize log data in dashboards.
What do you mean by auto-scaling?
AWS Auto Scaling analyzes your applications and automatically adjusts capacity to maintain steady, predictable performance at the lowest possible cost. Moreover, with AWS Auto Scaling, it’s easy to set up application scaling for multiple resources across multiple services in minutes. AWS Auto Scaling makes scaling simple with suggestions that allow you to optimize performance, costs, or balance between them. With AWS Auto Scaling, your applications always have the right resources at the right time.
What are the benefits of auto-scaling?
Setup scaling quickly: AWS Auto Scaling allows you to set target utilization levels for multiple resources in a single, intuitive interface. You can quickly see the average utilization of all of your scalable resources without having to navigate to other consoles.
Make smart scaling decisions: AWS Auto Scaling allows you to build scaling plans that automate how groups of different resources respond to changes in demand. You can optimize availability, costs, or a balance of both. AWS Auto Scaling automatically creates all of the scaling policies and sets targets for you based on your preference.
Automatically maintain performance: While using AWS Auto Scaling, you maintain optimal application performance and availability, even when workloads are periodic, unpredictable, or continuously changing. AWS Auto Scaling monitors your applications to make sure that they are operating at your desired performance levels.
Pay only for what you need: Auto Scaling helps you optimize your utilization and cost efficiencies when using AWS services so that you only pay for the resources you actually need. When demand drops, AWS Auto Scaling will automatically remove all excess resource capacity so you avoid overspending.
Is AWS Auto Scaling free?
Yes, AWS Auto Scaling is free to use, and allows you to optimize the costs of your AWS environment.
Differentiate between horizontal scaling and vertical scaling?
Horizontal Scaling is the act of changing the number of nodes in a computing system without changing the size of any individual node. Whereas, Vertical Scaling is increasing the size and computing power of a single instance or node without increasing the number of nodes or instances.
What is AWS Certificate Manager?
AWS Certificate Manager (ACM) handles the complexity of creating, storing, and renewing public and private certificates and keys that protect your AWS websites and applications. ACM certificates can secure singular domain names, multiple specific domain names, wildcard domains, or combinations of these. ACM wildcard certificates can protect an unlimited number of subdomains.
What do you mean by Amazon DynamoDB?
Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. It’s a fully managed, multi-region, multi-active, durable database with built-in security, backup and restore, and in-memory caching for internet-scale applications. DynamoDB can handle more than 10 trillion requests per day and can support peaks of more than 20 million requests per second.
What is Amazon CloudFront?
Amazon CloudFront is a web service that speeds up distribution of your static and dynamic web content, such as .html, .css, .js, and image files, to users. It delivers your content through a worldwide network of data centers called edge locations. When a user requests content that you’re serving with CloudFront, the request is routed to the edge location that provides the lowest latency, so that content is delivered with the best possible performance.
What are the AWS Tools for Reporting and Cost Optimization?
AWS provides several reporting and cost-optimization tools:
- Amazon cost Explorer
- AWS trusted advisor
- Amazon Cloudwatch
- AWS budget
- AWS cloudTrail
- Amazon S3 analytics
- Lastly, AWS cost and usage report
