Cloud Computing and its Importance

 

What is Cloud Computing?

The cloud consists of software and services that stay and operate on the Internet instead of having any physical elements like a local computer or on premise network servers. Cloud Adoption is a structured shift by organizations of minimizing expenditure, lowering risk and attaining scalability of database capabilities. Cloud adoption may be of various types in an organization, depending on the depth of adoption.

Benefits of Cloud Computing:

  • Cost Reduction: The cloud does not require the company to invest in new hardware, storage infrastructure and maintaining an in-house IT infrastructure (variable expenses). In the cloud, assets are made accessible on-demand and excessive resources can be returned/replaced, thus cutting costs. Likewise, the company may not splurge money on appointing IT staff to supervise the infrastructure.
  • Flexibility: Cloud computing offers more flexibility to businesses. Employees can obtain files using web-enabled devices such as smartphones, laptops, and notebooks. Sharing documents over the internet around the clock and to work online at any place has helped in internal and external collaborations of the business.
  • Scalability: Cloud enables users the ability to upscale or downscale infrastructure as and when required with ease, which results in optimal usage of resources. Companies can have high-performance resources available at the fingertips with professional clarifications without any up-front investment.
  • Mobility: Corporate data in the cloud can be easily saved, recovered, or organized with just a couple of clicks on their smartphones and other devices to keep up with clients and colleagues. Users get access to their works, 24/7, via any devices of their choice. This saves the IT team workload and results in customer satisfaction.
  • Agility: In Cloud computing, new IT resources are only a click away, which means that companies reduce the time spent to make those resources available to you just in minutes. These resources can then be more seamlessly and efficiently. This results in quick development of businesses’ market.
  • Disaster Recovery: There is no way one can prevent or control natural disasters which can cause great damage to the organization. But through cloud computing, the data can be stored in the cloud which guarantees that data will always available, even if your equipment like laptops or PCs, is damaged.

Platform-as-a-service (PaaS) refers to the supply on-demand software for developing, examining, delivering and managing applications.

Software-as-a-service (SaaS) is a method for delivering applications-as-a-service over the Interne (cloud computing) as per the demand and on a subscription basis.

Infrastructure as a Service (IaaS) is the most basic category of cloud computing services that allows you rent IT infrastructure: physical or virtual servers, storage and networking from a cloud provider on a pay-as-you-go basis.

Who uses Cloud Computing & Why?

Every type of companies use cloud computing irrespective of size, industry, It is used for a wide variety of cases, such as data backup, disaster recovery, email, virtual desktops, software development, etc. Even healthcare companies are using the cloud to create treatments for individual patients. Bank and financial sector companies are using the cloud to detect real-time fraud and its prevention. And video game makers are using the cloud to deliver online games to players around the world. One of the major use case is, running on premise data center is not simple, so the industry chose to use cloud computing. When it’s about scalability, cloud computing lays out a very resilient solution.

Security Concerns of Cloud Computing:

  1. Data Infringement: Data leakage can have grievous impact on company, its brand and reputation, employee, and customers’ hope and belief. Loss of vital intellectual property could have competitive and financial indications also.
  2. Seizing of Accounts: Attackers can hijack the account and use your credentials to remotely enter the data saved. They can counterfeit and tamper the data.
  3. Malware Injection: Cloud computing can be injected with malware scripts and codes which run as SaaS to cloud servers, through this the attackers can snoop in all the important information.
  4. Insufficient Training & Knowledge: Proper knowledge of cloud services should be provided to employees that manage database of the company. Deficiency of this may impact decisions relevant to privacy.
  5. Mutual Liability: Cloud surveillance is a common burden for the clients and service provider. This partnership between client and provider requires the client to take preventative actions to protect their data.
  6. Data Loss: Data on cloud services can be lost through a malicious attack, natural disaster, or a data wipe by the service provider. Losing essential facts and figures can be harmful to businesses that don’t have a recuperation plan.

Limitations of Cloud Computing:

  1. Internet Connection: In order to enjoy the features of cloud computing, your organization should always have an internet connection.
  2. Data confidentiality: Data & cloud protection must be powerful because then it won’t be perilous for data confidentiality.
  3. Downtime: Cloud computing systems are internet-situated, service outages are always an unfortunate possibility.
  4. Technical Issues: For technical issues, one has no choice but to call your hosted provider’s technical support.
  5. Vulnerable to attacks: Saving data in the cloud may cause consequential challenges of information heist since in the cloud every data of a company is online.

Some of the leading cloud providers like Amazon Web Services, Google Cloud, Microsoft Azure, etc are on the list of 50 connected cloud providers at DE-CIX Frankfurt.

 

A Complete Guide to an Internet Exchange Point

What does an Internet Exchange Point do? How does it work? What benefits does it provide, and why are more and more ISPs turning to them? Find out here:

  • What Is An Internet Exchange Point?

An Internet exchange point (IXP) is a network point at which Internet service providers and Content Delivery Networks exchange Internet traffic between their networks. At an IXP, all participants’ networks interconnect via common switching equipment instead of via each other’s internal infrastructure. Each participant in an IXP generally has two connections to every other participant’s networks: one for incoming traffic from peers at a lower speed which will be delivered internally, and another for sending higher-speed traffic to peers external to that organization. Thus, an IXP allows Internet service providers to exchange high volumes of traffic among themselves without incurring these costs on their own infrastructure or purchasing transit services from any other entity. Inbound data can come at higher speeds without being throttled by low-speed customer connections, and outbound data can be delivered more quickly with fewer hops across different networks.

  • History Of IXPs

The growth of Internet traffic over time is staggering: At its inception, on October 29th, 1969—the moment you’ve likely heard about as being the birth of the Internet—less than 5 kilobytes of data was transmitted over ARPANET. Forty years later (as of November 2010), ARPANET alone transferred an astounding 10 petabytes of data per day! As such, ISP-to-ISP connections using IXPs are not something we need today because there isn’t enough capacity built into the Internet infrastructure to support them yet. This will change soon, though. As Web 2.0 and social media continue to grow in popularity and importance, ISPs will start building more connections between each other so that every device, no matter where it is physically located in global networks, can access all services.

  • Benefits Of An Internet Exchange Point

IXPs allow organizations with direct connections to exchange Internet traffic without paying for transit. Traffic can be transported between exchanges using any protocol and topology with no restrictions. They provide a more efficient route of network traffic by eliminating intermediate providers. An IXP also eliminates congestion and packet loss in networks caused by downstream providers at peering points. Another major benefit of IXP is network resilience.

  • How Does It Work?

An Internet exchange point (IXP) is a large and geographically distributed network of IP routers through which many Internet service providers (ISPs) exchange Internet traffic. This architecture allows local ISPs to connect and exchange traffic with each other rather than send all traffic out through their international links. Traffic from one IXP can be quickly switched to another if there is a link failure or if there are problems with any of the equipment in a particular IXP.

  • Where Are They Located?

The simplest way of defining it is as a physical location where Internet service providers (ISPs) interconnect, forming a point through which data can pass directly between them. So, essentially, Internet exchange points are places where ISPs come together—usually in a neutral, third-party building or at least not in their own facilities—to trade traffic freely and without being charged.

To conclude

Internet Exchange Points are a great way to exchange internet traffic between various networks that do not have direct connections. It can significantly lower latency and increase overall network performance. This write-up aims to give you a basic understanding of what an Internet Exchange Point is, how it works, and its benefits.
