Amazon Web Services (AWS) comes under the most trusted cloud computing services. AWS is widely used by both start-ups and big enterprises. It offers various services like Networking, databases, analytics, management, computing, deployment, and security. Various common AWS mistakes made by organizations are listed below.
1. Manual Management of AWS Infrastructure
Sometimes developers set up AWS using web-management console, to manually produce the resources. As the actions are not reproducible here, if any damage persists it becomes very difficult to trace them. This can also by the effect of pre-existing Data.
To avoid this, AWS Cloud Formation is the best alternative here.AWS CloudFormation contains all the essential set of tools to automatically manage the infrastructure.
2. Selecting oversized instances
AWS Instances are the major resources we are getting here and definitely it is a basic need to run our system. It offers a variety of instances based on size. One needs to be clear about the quantity and size of the instances, as one also needs to keep track of each AWS instance.
Oversized instances can cost you too much money. To avoid this, one needs to be specific about the choices as per their requirement
3. Leaving instances running idle.
It has an amazing advantage, it has the ability to choose and supply instances according to the operational need of business. But the consequence of this facility is, sometimes users lose track of their instances. They forget to turn them off resulting in confusion to figure out the process and spiraling cost. To avoid this one needs to be careful while using various AWS instances.
4. Excessive EBS Snapshots
An EBS snapshot in AWS services plays a major role in the recovery process on system failures. It is a kind of backups which restores data on the system. The issue arises when too many snapshots are taken. This increases the unnecessary storage costs resulting in higher bills.
To avoid them, snapshots retention strategy using Amazon S3 lifecycle rules can be beneficial
5. Excessive EBS Volumes
In any cloud-based service, heaping up old or unused resources can be harmful to the management of this infrastructure. For example, EBS volumes are charged as per the use but the unused volumes can be the reason behind increment in bills as well as the performance-based issues in the system.
To avoid this, keep the calculated required volumes as per the future need.
6. Providing Inessential Privileges
Often, many employees are given admin rights. This can be dangerous in terms of AWS security privacy. User privileges should be checked on a regular basis. To ensure the integrity of the system, it is advised to avoid providing unnecessary controlling access.
To avoid this, It has a service called AWS Identity and Access Management (IAM). It manages every single access to AWS accounts eventually reducing security risks.
7. Not Maintaining the Logs
Often, AWS logs are ignored but whatever application has been used, logging of all the actions performed is necessary. This habit can be the saviour for system crashes and tracking the systems metrics.
To avoid this, enabling AWS CloudTrail can play a major in maintaining logs. It can also track the API calls from the AWS console.
8. Security Issues due to Misconfiguration
Sometimes It has to deal with various security flaws due to Misconfiguration of this in system infrastructure. It leaves various loopholes behind, which results in various security threats.
To avoid this, it is essential to regularly change the user credentials and passwords including, enabling two-factor authentication.
9. Ignoring Encryption
Often, it has been noticed that many enterprises do not enable encryption in their AWS cloud computing Infrastructure. Encryption is very important in order to create Relational Database Service (RDS), Elastic Block Storage (EBS), and to protect data in S3. Having misconfigured encryption is the same as having no encryption.
A properly configured encryption is necessary in order to avoid system security threats.
10. Ignoring the future Outage issues
It has a feature called AWS Availability Zones; it simply distributes the user’s workload across various data centers. This simply lowers the risk of an outage.
So, to avoid outage one must think about spreading their workload within a given region via AWS Availability Zone.
