Anyone who wants to start using cloud technology must first learn the principles of AWS. The following AWS pointers and advice can speed up your start and help you avoid common blunders. You’ll get a deeper comprehension of AWS cloud security fundamentals as well as choices for controlling the costs associated with your AWS subscription.
1. Enable MFA for root user
Each AWS account has one user with complete control over all other users and services. Root user. Documentation advises against utilizing root for frequent tasks, including administrative ones (…)
Use root’s credentials for a few account and service management activities, then store them.
Our AWS root user has full access. Virtual computers to database erasure The root user is a target for evildoers. Electric AMGshould be enabled for the root user of a new AWS account. For added security, a hardware token or virtual device can be used (a smartphone app). Once MFA is enabled, logging in as root will require a code from a different device (or “factor”). Duo, Authy, and Google Authenticator are popular apps.
Enabling MFA reduces account attacks.
2. Create a billing alarm
Every cloud engineer fears getting a bill for unanticipated services. Maybe the wrong EC2 instance is running, or we set up a costly database service. If we start a virtual computer, we pay per hour or per GB of data in the object storage. If we don’t shut down dormant virtual machines or remove obsolete data from S3, we’ll waste money. improvement services We can only set price point alarms because AWS will charge us. We can monitor if usage is increasing and reaching a specific amount. When our monthly expenses exceed our limit, we’ll receive an email or SMS so we can take action.
3. Get familiar with Identity and Access Management
The Identity and Access Management (IAM) service performs all authentication and authorization for communications with AWS. It lets us manage AWS access granularly. Several situations
- Is Bob allowed to launch a new virtual server?
- Is the application permitted to store data on the object store?
- Is Mary authorized to access customer information stored in the NoSQL database?
Understanding IAM ideas and following advised practices are essential. We will be doing ourselves a great favor if we set aside time to research and properly understand the Identity and Access Management service right immediately.
4. Make use of the Free Tier
You can start using AWS right away without having to pay anything. Many services are provided without charge for the first year of a newly opened account. Launch a virtual machine on AWS for 750 hours per month for the first year without paying anything. AWS will provide you with up to 5 GB of free object store storage for the first year. Use a Lambda function up to one million times or freely store up to 25 GB in a NoSQL database.
It is strongly encouraged to use the Free Tier to learn about these services as a way to get started.
5. Choose the right region(s)
AWS has data centers all over the world that are separated into regions. We should think about which region would be best for the specific use case before utilizing an AWS service. Consider the following factors while choosing a region:
- Latency: Which region is closest to your customers?
- Availability of services: Are all the services you want to use available in the region?
- Compliance: Are you allowed to store and process data in the jurisdiction of the region?
- Costs: What are the costs for running your workload in the region?
6. Enable CloudTrail
Use CloudTrail to keep track of each AWS API request. Each time a team member makes a change to the cloud infrastructure, a log event is kept (for instance, by changing the firewall configuration). This makes it possible for us to investigate security issues or troubleshoot faults.
After being turned on, CloudTrail creates log files that can be reviewed at a later time.
For added security, it is suggested that you send a copy of the CloudTrail logs to a second AWS account with less access. Attackers are unable to remove access history by doing this.
7. Learn about essential services
Cloud services can be split into the following categories:
- Networking
- Compute
- Storage
- Database
- Security
Under these categories, AWS offers more than 200 different services. Start your journey by learning about the most popular:
- Amazon Virtual Private Cloud (VPC)
- Amazon Elastic Compute Cloud (EC2)
- Amazon Simple Storage Service (S3)
- Amazon Relational Database Service (RDS)
- AWS Identity and Access Management (IAM)
8. Install and configure the AWS Command Line Interface (CLI)
AWS CLI is the simplest way to interact with AWS services. The AWS Management Console is used for web-browser and web-interface interactions with AWS. When scripting, the AWS CLI is useful. Manually invoked or contained in bash scripts.
First, install and configure AWS CLI.
9. Aim for automation
AWS allows us to automate our cloud design, from launching virtual machines to establishing the networking infrastructure. Automation enhances our infrastructure and reduces administrative labour. Automation will maximize AWS consumption (try AWS CloudFormation or Cloud Development Kit).
10. Consult the Trusted Advisor
AWS-savvy cloud architects should regularly review our accounts. Alternatively, we can use AWS Trusted Advisor. AWS account specialist is automated. To optimize an AWS account, use the following AWS Trusted Advisor categories:
- Cost Optimization
- Performance
- Security
- Fault Tolerance
Check Trusted Advisor’s findings often.
Cloud travel can be daunting at first. The number of offerings and lack of direction might be daunting. With these tips, you can speed up the process and feel more confident using AWS.
