7. List different types of Cloud Services

Cloud services can be broadly classified into three categories: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). Here is a brief overview of each type of cloud service:

1. Infrastructure as a Service (IaaS): IaaS is a type of cloud service that provides infrastructure resources such as computing, storage, and networking on a pay-as-you-go basis. IaaS providers typically offer a range of options for configuring and customizing these resources to meet the needs of your applications and workloads. Examples of IaaS providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).
2. Platform as a Service (PaaS): PaaS is a type of cloud service that provides a platform for developing, deploying, and managing applications on the cloud. PaaS providers typically offer a range of tools and resources for building, testing, and deploying applications, as well as services for managing and scaling them. Examples of PaaS providers include AWS Elastic Beanstalk, Microsoft Azure App Service, and Google App Engine.
3. Software as a Service (SaaS): SaaS is a type of cloud service that provides software applications that can be accessed over the internet. SaaS providers typically offer a range of applications that can be used for tasks such as productivity, collaboration, customer relationship management, and more. Examples of SaaS providers include Microsoft Office 365, Salesforce, and Google G Suite.

There are many other types of cloud services available, and the specific offerings can vary significantly among different providers. Some other examples of cloud services include data as a service (DaaS), security as a service (SECaaS), and communication as a service (CaaS)

 8. How can I monitor my AWS resources in near real-time?

You may gather and keep track of measurements in a timeframe that is close to real-time by using AWS CloudWatch. The information regarding its metrics is kept as time-series data points. In addition, each data point in a time series is accompanied by a timestamp as well as a unit of measurement.  

 9. How to delete alarms in AWS CloudWatch Console?

Use the following command to delete the alarms in AWS CloudWatch Console:

aws cloudwatch delete-alarms --region us-east-2 --alarm-names ...

10. What is Power User Access in AWS?

The owner of the AWS resources will be comparable to an administrator user. It can grant access to other users for the AWS resources that add, delete, change, or inspect the resources. Administrator access is provided with Power User Access but without the ability to control users and permissions. 

In other words, a user who has Power User Access can create, delete, change, or view the resources but cannot allow other users access.

No, CloudWatch does not automatically clean up old logs in the background. When you no longer require the old logs, you must manually delete them from the system

17. How to get additional lines of context in a CloudWatch Insights query?

In AWS CloudWatch Insights, you can use the context function to retrieve additional lines of context around a specific event in your log data. The context function takes two arguments: the number of lines of context to retrieve before and after the event.

Here is an example of a CloudWatch Insights query that retrieves three lines of context before and after each event:

fields @timestamp, @message
| sort @timestamp desc
| limit 20
| context 3 3

This query will display the timestamp and message fields for the most recent 20 events in your log data, sorted in descending order by timestamp. It will also display three lines of context before and after each event.

You can adjust the number of lines of context by changing the arguments of the context function. For example, to retrieve five lines of context before and after each event, you can use the following query:

fields @timestamp, @message
| sort @timestamp desc
| limit 20
| context 5 5
