How Green Data Centers Achieve Efficiency

Why Going Green is a Good Move for Datacenters

How Green Data Centers Achieve Efficiency

Data centers have matured immensely over the past decade with today's data centers being greener than ever. Pike Research mentions that the green data center market was worth $17.1 billion in 2012. The green data center economy is expected to grow rapidly throughout this decade. Pike Research estimates that the total market value for green data centers will increase to $45 billion by 2016.

Green data centers are crucial for the advancement of computing technology. Data centers are being built all over the world to house large public computing infrastructures such as Microsoft Azure, Google Cloud or Amazon AWS. Each of these organizations has their own methodologies in place on how to create a greener data center, but some have faced criticism that they aren't doing quite enough. Regardless of who constructs the data center, the keys to building data center revolve around the following two key ideas:

Using Free Cooling to Achieve Energy Efficiency

Google mentions that they employ a free cooling technique in their data centers. This isn't specific to Google; the idea of using free cooling techniques is an industry standard. The process of free cooling refers to methods that remove heat from the data center without the use of an air conditioner or a chiller. Companies that build out green data centers must first take advantage of the free methods available to cool their equipment. Availability of wind, water and thermal reservoirs add specific advantages to those looking to build out green data centers. Experts agree that the ability to cool your data center is where the most opportunity for saving energy exists.

Managing Variables inside the Facility

Today's data centers are built using the most efficient methodologies in mind. One of the biggest misconceptions about data centers is that they must be kept chilly. Believe it or not, green data centers set their thermostat high in order to save energy. The average temperature inside of a Google data center is 80 degrees. Google humorously notes that they ask their data center employees to wear shorts to work because of how warm it is inside of their data centers.

Today's data centers can safely operate in the 80 degree range without risking equipment failures. The warm nature of green data centers presents the potential for hot spots to begin popping up inside the data center. Thermal modeling is used to detect hot spots and airflow is directed towards these hot spots in order to mitigate the risks of overheating. Airflow architecture is essential in keeping specific systems cooled at their appropriate temperatures.

The dynamic nature of the cloud means that change is a constant when it comes to modern cloud-based infrastructure. Delivering modern applications to end users, therefore, is a constantly shifting challenge. Delivery automation helps IT Ops teams ensure that apps are providing an optimal end user experience over hybrid-cloud and multi-cloud environments, no matter what the current state of the infrastructure is. To employ a delivery automation strategy that reflects your business rules, making r...
Modern software design has fundamentally changed how we manage applications, causing many to turn to containers as the new virtual machine for resource management. As container adoption grows beyond stateless applications to stateful workloads, the need for persistent storage is foundational - something customers routinely cite as a top pain point. In his session at @DevOpsSummit at 21st Cloud Expo, Bill Borsari, Head of Systems Engineering at Datera, explored how organizations can reap the bene...
Kubernetes is an open source system for automating deployment, scaling, and management of containerized applications. Kubernetes was originally built by Google, leveraging years of experience with managing container workloads, and is now a Cloud Native Compute Foundation (CNCF) project. Kubernetes has been widely adopted by the community, supported on all major public and private cloud providers, and is gaining rapid adoption in enterprises. However, Kubernetes may seem intimidating and complex ...
In a recent survey, Sumo Logic surveyed 1,500 customers who employ cloud services such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). According to the survey, a quarter of the respondents have already deployed Docker containers and nearly as many (23 percent) are employing the AWS Lambda serverless computing framework. It’s clear: serverless is here to stay. The adoption does come with some needed changes, within both application development and operations. Tha...
In his session at 21st Cloud Expo, Michael Burley, a Senior Business Development Executive in IT Services at NetApp, described how NetApp designed a three-year program of work to migrate 25PB of a major telco's enterprise data to a new STaaS platform, and then secured a long-term contract to manage and operate the platform. This significant program blended the best of NetApp’s solutions and services capabilities to enable this telco’s successful adoption of private cloud storage and launching ...

The past few years have brought a sea change in the way applications are architected, developed, and consumed—increasing both the complexity of testing and the business impact of software failures. How can software testing professionals keep pace with modern application delivery, given the trends that impact both architectures (cloud, microservices, and APIs) and processes (DevOps, agile, and continuous delivery)? This is where continuous testing comes in. D

You know you need the cloud, but you’re hesitant to simply dump everything at Amazon since you know that not all workloads are suitable for cloud. You know that you want the kind of ease of use and scalability that you get with public cloud, but your applications are architected in a way that makes the public cloud a non-starter. You’re looking at private cloud solutions based on hyperconverged infrastructure, but you’re concerned with the limits inherent in those technologies.
