Multi-cloud Spending: 8 Tips To Lower Cost

A multi-cloud approach is nothing but leveraging two or more cloud platforms for meeting the various business requirements of an enterprise. The multi-cloud IT environment incorporates different clouds from multiple vendors and negates the dependence on a single public cloud service provider. Thus enterprises can choose specific services from multiple public clouds and reap the benefits of each.

Given its affordability and agility, most enterprises opt for a multi-cloud approach in cloud computing now. A 2018 survey on the public cloud services market points out that 81% of the respondents use services from two or more providers. Subsequently, the cloud computing services market has reported incredible growth in recent times. The worldwide public cloud services market is all set to reach $500 billion in the next four years, according to IDC.

By choosing multi-cloud solutions strategically, enterprises can optimize the benefits of cloud computing and aim for some key competitive advantages. They can avoid the lengthy and cumbersome processes involved in buying, installing and testing high-priced systems. The IaaS and PaaS solutions have become a windfall for the enterprise’s budget as it does not incur huge up-front capital expenditure.

However, cost optimization is still a challenge while facilitating a multi-cloud environment and a large number of enterprises end up overpaying with or without realizing it. The below-mentioned tips would help you ensure the money is spent wisely on cloud computing services.

  • Deactivate underused or unattached resources

Most organizations tend to get wrong with simple things which turn out to be the root cause for needless spending and resource wastage. The first step to cost optimization in your cloud strategy is to identify underutilized resources that you have been paying for.

Enterprises often continue to pay for resources that have been purchased earlier but are no longer useful. Identifying such unused and unattached resources and deactivating it on a regular basis brings you one step closer to cost optimization. If needed, you can deploy automated cloud management tools that are largely helpful in providing the analytics needed to optimize the cloud spending and cut costs on an ongoing basis.

  • Figure out idle instances

Another key cost optimization strategy is to identify the idle computing instances and consolidate them into fewer instances. An idle computing instance may require a CPU utilization level of 1-5%, but you may be billed by the service provider for 100% for the same instance.

Every enterprise will have such non-production instances that constitute unnecessary storage space and lead to overpaying. Re-evaluating your resource allocations regularly and removing unnecessary storage may help you save money significantly. Resource allocation is not only a matter of CPU and memory but also it is linked to the storage, network, and various other factors.

  • Deploy monitoring mechanisms

The key to efficient cost reduction in cloud computing technology lies in proactive monitoring. A comprehensive view of the cloud usage helps enterprises to monitor and minimize unnecessary spending. You can make use of various mechanisms for monitoring computing demand.

For instance, you can use a heatmap to understand the highs and lows in computing visually. This heat map indicates the start and stop times which in turn lead to reduced costs. You can also deploy automated tools that help organizations to schedule instances to start and stop. By following a heatmap, you can understand whether it is safe to shut down servers on holidays or weekends.

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.

How Do I Pass the AWS Solutions Architect Associate Exam? Careerera

The AWS solutions architect associate exam is one of the most difficult certification exams in the world. There are many certifications for various things such as the PMP certification and the CISSP certification, but it is the AWS solutions architect associate exam which takes the crown when it comes to difficulty.

How to Qualify an AWS Certified Solutions Architect Associate Exam?

Naturally, given the difficulty of the exam many people wonder, “How Do I Pass the AWS Solutions Architect Associate Exam?” on the first attempt. This is a very valid question and, in this article, we will discuss all the ways in which one can maximize his chances of passing the AWS solutions architect associate exam in the first attempt.

Before starting we must remember one thing – the AWS platform is a beast of a platform and is vast beyond comprehension. So, for a beginner looking to take the AWS solutions architect associate exam it will not be possible to cover all the topics and services related to the AWS platform.

However, one can make one’s best attempt to cover all the core concepts and topics which are most relevant and pertinent to the AWS platform. A candidate for the AWS solutions architect associate exam in particular should keep himself updated on all the most recent advances and developments in the field of AWS.

Which services are tested most frequently on the exam?

  1. Amazon EC2 -

This service is used to create virtual machines which are offsite. It is also used to manage things such as ports, security, and storage because of its many features. It allows the users to utilize AWS’ vast computing capabilities on-demand. With a ‘scale as you grow’ philosophy the user is not trapped into an agreement in which they will have to purchase excessive resources from Amazon.
They only have to make use of as many resources as they need. The Amazon EC2 web interface allows the software developers to configure and resize the compute machines to their heart’s content with minimal friction and absolutely no confusion whatsoever. All decent AWS Solutions Architect Associate Certification courses teach how to make use of this service.

  1. Amazon RDS -

The full form of Amazon RDS is Amazon Relational Database Service. It is an extremely useful service launched by Amazon. It is used by software developers to create a database with all the features of a full-fledged offline database in a matter of minutes.

The main purpose of Amazon RDS is to set up relational databases in the cloud. These databases can be set up, operated, and scaled very easily and very smoothly. Amazon provides a very seamless and slick interface which is ideal for operating the databases thus created.
