What is Eucalyptus Cloud?

by Ziuby

Eucalyptus is free and open source computer software for building Amazon Web Services (AWS)-compatible private and hybrid cloud computing environments marketed by the company Eucalyptus Systems. Eucalyptus is the acronym for Elastic Utility Computing Architecture for Linking Your Programs To Useful Systems.                                                     

The best part is, it is compatible with Amazon Web Services (AWS) API.
And we can manage Eucalyptus or Amazon Instances using Eucalyptus commands. Users can also move their instances between Eucalyptus Private Cloud and Amazon EC2 instances to create hybrid cloud.




                                           

 Key Benefits:-
•    Increase agility
•    Lower Cost
•    Improve Security

What is Cloud Computing?

Getting frustrated with multiple dedicated servers? Here is the solution i.e. cloud. Migrate your dedicated server in one server and simply launch the instances on that server and perform the task on that launched instance.

Cloud technology is the fast growing technology in the IT industry. Because it requires less resources as compare to dedicated servers and its cost consuming as compare to dedicated servers. But yes it requires expertise to manage these cloud systems. Cloud computing is very deep and vast concept.

Generally there are three types of cloud.

1) Private Cloud
2) Public Cloud
3) Hybrid Cloud


1) Private Cloud :- Private cloud is cloud infrastructure dedicated to a particular organization. Private clouds allow businesses to host applications in the cloud, while addressing concerns regarding data security and control, which is often lacking in a public cloud environment. It is not shared with other organizations,   whether managed internally or by a third-party, and it can be hosted internally or externally.
There are two variations of private clouds:-

On-Premise Private Cloud :- This part is related to that organisation who is actually developing the cloud on their own premices. There are some opensource tools like OpenStack or Eucalyptus which helps us to build the private cloud on our own premises. But again role doesn't end here. The maintenance and security is much needed for that cloud. 
     

Externally Hosted Private Cloud :- Externally hosted private clouds are also exclusively used by one organization, but are hosted by a third party specializing in cloud infrastructure. Here security part is totally related to providers. We need to only pay for our use. 
                       
2) Public Cloud :- Public clouds are made available to the general public by a service provider who hosts the cloud infrastructure. Generally, There are few public cloud service providers like Amazon Web Services(AWS), Microsoft Azure, Google g cloud, i cloud. These companies provide some services on cloud only these services are accessible to their customers public cloud provides generally follows the method the low-cost module or you can only pay according to your use.On public cloud we can access the infrastructure virtually or we can do changes or modify according to our requirement.
    

The best example of this is AWS EC2 service. The basic thing behind public cloud is we can access its services or modules from anywhere at anytime. In public cloud we can even build the Virtual Private Cloud(VPC).

3) Hybrid Cloud :-  Hybrid cloud is the integration of private cloud and public cloud. In a hybrid cloud, you can leverage third party cloud providers in either a full or partial manner, increasing the flexibility of computing. Augmenting a traditional private cloud with the resources of a public cloud can be used to manage any unexpected surges in workload. Hybrid cloud uses both on premises resource and off premises resource. The simple thinking behind is whenever on premises server goes down then automatically it will shift on public cloud. But here we always need to take snapshot on our own premises.

A look into Green Computing for #2015 : From Current to Future Trends

 by Ziuby

The term ‘Green Computing’ is the study and practices that covers the computing lifecycle from cradle to grave. It start from design to manufacturing to use of equipment and then safely disposing-off computers, related devices, networking and communications equipment’s efficiently and effectively with negligible or no impact on the environment.

Current trends of #GreenComputing are towards efficient utilization of resources. Energy is considered as the main resource and the carbon footprints are considered the major threads to environment.

There are several areas where researchers are putting lots of efforts to achieve desired

1. Energy Consumption
2. E-waste Recycling.
3. Data Center Consolidation & Optimization
4. Virtualization
5. IT Products and Eco labeling

The reason to focus and analyze Future Trends is because of growth in computing needs, energy cost and global warming and this shift is great challenge for IT industry. The future of Green Computing in #2015 is going to be based on efficiency, rather than reduction in consumption. The primarily focus of Green IT is in the organization’s self interest in energy cost reduction, at #DataCenter and at desktops, and the result of which is the corresponding reduction in carbon generation.The secondary focus of Green IT needs to focus beyond energy use in the Data Center and #CloudComputing the focus should be on innovation and improving alignment with overall corporate social responsibility efforts.

There are few efforts, which all enterprises are supposed to take care of

1. Certifications
2. Cloud Computing
3. Product Longevity
4. Power Management Tools
5. Leveraging Unused Computer Resource
6. Data Compression
7. Applications

Technology is not a passive observer, but it is an active contributor in achieving the goals of Green Computing. One must make conscious efforts to make the world a better place, in this case the digital world too. IT industry in #India have started to take interest in the ways
