Now a cliche but once a reality, it turns out that the canaries, like other birds, are much more sensitive to poisonous gases than humans. The birds were brought down into the coal mine and acted as an indicator and early warning of possible danger to the British miners.
An electronic detection system later replaced the birds, but these birds served an essential role for decades.
The public cloud has changed the way organizations deliver, respond, and represent their customers, and organizations are building an early warning systems approach to their cloud. The teams and systems that make up this strategy are Cloud Center of Excellent (CoE), which provides centralized controls, tools, and best practices.
The purpose of these teams is to accelerate cloud adoption by centralizing expertise while reducing costs and risk (Flexera, 2021).
Unlike the canaries that provide chaotic monitoring of harmful gasses, enterprises have tools that offer next-level proactive and predictive monitoring. These systems allow organizations to understand the complexity of their cloud and oversee across multiple business units and functional areas.
Well, it’s not a cute bird, but it does overcome the spiraling complexity of cloud, hybrid cloud, and traditional IT. AppDynamics, ThousandEyes, and Intersight Workload Optimizer make up Cisco’s Full-Stack Observability platform. Connecting the dots up and down the “stack”-from the customer or employee-facing application, all the way down to the lowest level infrastructure (compute, storage, networking, and public internet).
When we consider the technical environment we live in, we recognize the need to monitor the entire IT estate. Like the canaries in the coal mine, the answer is to predict and identify an issue before it adversely affects customers and businesses.
The AWS Certified Cloud Practioner Exam (CLF-C01) is an entry-level exam, 65 questions of multiple-choice, multiple response questions. The test is intended for individuals who have basic knowledge of the AWS platform and the available services, conceptual AWS cloud architectural principles, security, common use cases, and compliance.
The exam includes four domains; Cloud Concepts, Security and Compliance, Technology, and Billing and Pricing. Each section of the domain has a specific weighting, so some sections have more questions than others.
I recently sat and passed the AWS Cloud Practioner Exam and wanted to provide an overview of the exam, share with you my study resources and the outlook on the certification.
What to expect
The exam’s primary focus will be on identifying the AWS core services like EC2, connection methods like AWS Direct Connect, EBS, S3 and S3 classes, CloudWatch, Trusted Advisor. The previous isn’t a comprehensive list but indeed services you should know. You will be tested on your understanding and identifying AWS-specific services. It would be best to understand how they work at a high level rather than understanding how to configure or deploy the services. Although, this would be an added value if you did.
You will want to know the advantages of cloud computing the way AWS defines it. AWS defines six advantages of cloud computing:
Trade upfront expenses for variable expenses
Stop spending money to run and maintain data centers
Stop guessing capacity
Benefit from massive economies of scale
Increase speed and agility
Go global in minutes
Lastly, I recommend understanding the shared responsibility model.
The shared responsibility model divides into customer responsibilities (commonly referred to as “security in the cloud”) and AWS responsibilities (commonly referred to as “security of the cloud”).
You can think of this model as being similar to the division of responsibilities between a homeowner and a homebuilder. The builder (AWS) is responsible for constructing your house and ensuring that it is solidly built. As the homeowner (the customer), it is your responsibility to secure everything in the house by ensuring that the doors are closed and locked.
To help you prepare for AWS exams, AWS has a training and certification section. Fortunately, the training for the AWS practitioner exam is free, and it’s fantastic. The AWS Cloud Practitioner Essentials course is roughly six hours if you read and watch the videos without taking notes. It would be best if you had an Amazon.com account as it is required to access the material. With note-taking, it took me about 20 hours to complete the course.
The video content is incredible. It offers a video transcript so that you don’t have to constantly rewind the video as you take your notes because of something you’ve missed.
Although you can pass the exam with this resource alone, I recommend David Tucker’s course, “Understanding AWS Core Services” on Pluralsight. I like this course because it solidifies your understanding of the services exposed during the AWS Cloud Practitioner Essentials training. It also has a section for you to try practice questions to gauge your readiness. I would do this after completing the AWS training material.
Outlook on CLF-C01
Today’s applications use cloud resources to provide the best in bread user experience, data quality, and high-availability. For the same benefits that the applications leverage the cloud, so do organizations and enterprises. It’s essential for us as engineers to design well-architected networks both on-prem and in the cloud. The skills obtained from working through the AWS Cloud Practioner Exam won’t make you a cloud architect alone. However, it will enable you to be comfortable speaking on cloud-specific technologies, why they exist, and some of the benefits over traditional on-premise technology.
AWS Cloud practitioner provides a tremendous foundational approach to cloud and AWS-specific services and products. It is a test that I recommend to any engineer.
