The post Cloud Data Center Locations for Top 3 CSPs (AWS, Azure & Google) appeared first on Techyaz.com.

Cloud Computing brings best in breed technologies mesh to provide high availability, durability and capacity with minimum time frame. In simple words your traditional data center (DC) would have flew down from on-premise to somewhere with big giants Cloud Service Providers DC like GCP (Google Cloud Platform), AWS (Amazon Web Services), Azure, IBM, Salesforce etc.

Why Should You Learn Cloud Computing?

As i mentioned above, Cloud Computing is growing faster than ever and creating lot of high paying jobs. The reason behind its popularity is its Pay As You Use model.

All cloud services are running on “Pay As You Use” model. You only pay for the services till you are using and can increase/decrease the usage capacity in few hours only. The Cloud Computing takes away hassle of procurement of servers, software’s & resources. It also removes the need of building, managing & maintenance of Data centres that is why most of the organizations are adopting cloud computing these days.

As more organizations will move to cloud, more cloud related jobs or opportunities will arise. So, it is imperative to learn cloud computing technology so that you can make use of it in your IT career. The added advantage of learning cloud is that you can bring value to your organization and its clients.

Prerequisites to Learn Cloud Computing

Today I will brief you about the skills needed to learn cloud and build promising career in it. Cloud can add value to your CV/Resume. Every IT professional need to have some familiarity with cloud. It has become an essential part of Information Technology. We as Digital Users are leveraging cloud Technology every day in our life. The most common example is social media, mails, music, YouTube, Facebook, Instagram, Twitter, News etc. Everything where data is stored in huge size is using cloud technology in the background.

Cloud Computing services falls into three categories:

• Infrastructure as a Service (IaaS),
• Platform as a Service (PaaS)
• Software as a Service (SaaS).

Although this article is very much applicable to all three categories for learning standpoint but primarily we will talk and refer about IaaS (Infrastructure as a Service) model. Infrastructure as a service (IaaS) is a form of cloud computing that provides virtualized compute resources over the internet following pay per use model.

As in earlier days Data center had multiple roles and responsibilities, similarly in cloud you can get similar technology, roles and career. If you belongs to IT Infrastructure services, then you  can pursue your career in IaaS cloud computing.

One can learn cloud as a beginner even if you have very basic skills in computers, prior experience in IT is an added advantage.

To begin with cloud there are three-important area to cover:

• Virtualization concepts
• Networking in virtual environment
• Operating systems (Linux & Windows)

Virtualization

It is important to understand how virtualized environment operates. In cloud context, virtual machines lie over and above hypervisor layer. Multiple VM’s shared same physical hardware and all the network equipment but are isolated or virtually separated from the other client machines using hypervisor technology. Virtualization means every type of application or workload which needed physical machines in past now can run by using shared resources across many clients. For more information refer to

Networking

The most important aspect of cloud is to understand cloud networking. It is very difficult section in cloud, and even those with some robust skills, typically require time to fully understand it.

Operating System (Linux & Windows)

Hands on experience on Linux and Windows is with excellent command lines skills is must before begin journey in cloud computing. One must begin with above three concepts to enter cloud computing.

How to Start Learning Cloud Computing?

The very first thing you need to do is, you need to decide the cloud service provider for which you want to learn and pursue distinct roles. There are many Cloud service providers in the market. You can choose any of them but it’s always wise to choose from top 3 service providers. Currently, Amazon is top cloud service provider in the market followed by Microsoft. Below are the names of some popular cloud service providers.

1. Amazon Web Services (AWS)
2. Microsoft Azure
3. IBM Cloud
4. Google Cloud Platform (GCP)
5. Salesforce

Once you have chosen the right cloud service provider then you should focus on the distinct domains. For example, if you had prior experience in networks you can choose to become Cloud Network Architect role and start focusing on CSP network services. If you are a system administrator then you can pursue Cloud System Administrator role. Below is the list of some cloud computing roles.

You can choose any roles given below as per your choice and are of interest. It would be an added advantage if you choose a domain in which you have some knowledge. The Distinct Technical roles which you can pursue in cloud are given below.

The post How to Learn Cloud Computing? appeared first on Techyaz.com.

Here I am going to answer all these questions and explaining about Cloud Security in this context.

Is your data secure in Cloud environment?

Yes, your data will be secured in cloud environment if you can design security solution/configurations leveraging public cloud providers features and third-party tools efficiently.

The amount of security configuration work you must do will varies, depending on what kind of cloud services you select and how sensitive your data is.

Security in Cloud creates a shared responsibility model between the customer and Cloud Service Provider (CSP). CSPs are responsible for securing the infrastructure (hardware, software, networks, and facilities of their Data center) that supports the cloud and you will be responsible for anything you put on the cloud or connect to the cloud (Data, Operating System, softwares, tools, License, Access, Credentials, authentication, encryption etc.)

Is your data in Cloud Hackable?

No, cloud systems are not hackable in terms of technology, hardware and network services provided by cloud provider. However, if security configurations are not done accurately by the user then loopholes in security may lead vulnerability in your cloud environment.

Can your data be disclosed by the Cloud Service Provider?

Your content/data will not be disclosed unless service provider required to do so to comply with the law of the country or a valid and binding order of a governmental or regulatory body. Unless prohibited from doing so or there is clear indication of illegal conduct about the use of CSP’s products or services. CSP notifies customers before disclosing customer content so they can seek protection from disclosure.

To understand all above and similar security related concerns you should first understand Cloud Security. Let’s discuss what is cloud security and how many domains we need to take care from cloud security point of view.

What is Cloud Security?

As every second your information/data travel through cloud and from different locations, networks and regions. We need to ensure it is not leaked in process of transmission from one place to other. Typically, all firms are well verse about physical and technical security of their On-premise data center. Similarly, cloud services and Infrastructure need to be secured to protect the confidentiality, integrity, and availability of your or your client data.

In Cloud context, security is a shared responsibility between the Cloud Service Provider (CSP) and its users/customers. CSPs take care of physical and logical security of its underlying hardware until Hypervisor layer. However, anything above Operating System is Client responsibility because customer owns the data and service provider has no access to it. Although it also varies in each model of Cloud Computing for some services.

Cloud Security is all about leveraging security features and tools to design and build a secure cloud environment to protect the privacy and integrity of cloud customers and their data. Cloud Security is blend of technologies and policies designed to adhere and regulate compliance rules and protect information, data applications and infrastructure associated with Cloud Computing use.

Cloud Security Categories

From cloud security perspective, below are the cloud security domains or categories that needs to be considered while building cloud environment.

1. Physical Security
2. Network security
3. System Security
4. Application Security
5. Data Security
6. Identity and Access management
7. Encryptions
8. Security operations

Each ownership for each type of security in cloud varies in each model of Cloud. You can see who is responsible for  what in each cloud model in below image.

1. Physical Security- is the protection of hardware, software, networks and data from physical actions and events that could cause serious loss or damage to an enterprise, agency or institution. CSPs are responsible to take care of this security.
2. Network Security – Includes data security in transit to and from the public cloud provider. It means designing and building network configuration and its elements allowing a secure access to cloud resources from your on-premise Data centers, Office, Internet etc. This security is shared responsibility between CSPs & Customer.
3. System Security- This capability covers operating system hardening, protection and policy control. The host security at PaaS and SaaS Level are transferred to CSP.
4. Application Security – It’s a shared responsibility in cloud context to protect the application running over the cloud. Based on type of cloud model application security is managed, for e.g in SaaS cloud provider will manage the security of the application. While at the PaaS level platform security will be managed by CSP and deployed application will be customer responsibility.
5. Data Security – Data security capability includes securing data in transit and at rest it to avoid data loss and exposure.
6. Identity and Access management- This capability evolves around authentication, verification and authorization of cloud resources.
7. Encryptions – As all communications between regions is across public Internet infrastructure; therefore, appropriate encryption methods should be used to protect sensitive data.
8. Security operations- Governance and strategic direction on security policies, risk assessment and its maintenance.

Choose Cloud Service Provider considering Data Security, Information Security and Quality Assurance?

Its depends on data and its criticality in terms of sensitivity, availability & durability requirement. For choosing most reliable cloud service provider we must consider CSP’s accreditations, security certifications and third party audit assessment reports. All major cloud service provider share their policies accreditation on data privacy, security, durability, availability information on their respective portals under valid Non-disclosure agreement. These certifications are global and can be achieved through periodic rigorous external audit accredited certification bodies based on NIST (National Industrial Security Program Operating Manual) global standards.

Some of the Most popular Cloud Service Provider Accreditations and Certification for cloud computing compliance and security are given in attached article. Read it to understand Cloud Accreditations and Certification that will finally help you to choose right Cloud Service Provider.

Cloud Computing

Cloud Computing atmosphere is all about getting compute for e.g. (Storage, Software, Platform, CPU, RAM, Processor, network, Cluster etc.) using Internet anywhere, anytime and in any size. Cloud provides unlimited compute services with pay as per use model. Cloud bring best in breed technologies mesh to provide high availability, high durability and high capacity with minimum time frame, in simple words your traditional data center (DC) would have flew down from on-premise to somewhere with big giants Cloud Service Providers DC like Google, AWS, Azure etc.

Benefits of Cloud Computing

There are many benefits of Cloud Computing. It is a big shift from the traditional way businesses think about IT resources.

1. Time -Most cloud computing services are provided on demand, so even vast amounts of computing resources can be provisioned in minutes, certainly with just a few mouse clicks, giving businesses a lot of flexibility and taking the pressure off capacity planning
2. Cost – Cloud Computing removes the investment expense of procurement of hardware and software and setting up and running onsite datacenters—the racks of servers, 24/7 electricity for power and cooling, the IT experts for managing the infrastructure, Hardware maintenance, Physical security etc.
3. Scalability -The benefits of cloud computing services include the ability to scale elastically. In cloud speak, that means delivering the right amount of IT resources—for example, computing power, storage, bandwidth—right when it’s needed and from the right geographic location.
4. Productivity-On-site data centers typically requires high maintenance, technology upgrade and heavy investment as it need lot of “racking and stacking”—hardware setup, software patching and other time-consuming IT management tasks. Cloud removes the need for many of these tasks, so IT teams can spend time on achieving business goals. Moving to the cloud gives access to enterprise-class technology, for everyone anywhere anytime.
5. High Performance-The biggest cloud computing services run on a worldwide network of secure datacenters, which are regularly upgraded to the latest generation of fast and efficient computing hardware. This offers several benefits over a single corporate datacenter, including reduced network latency for applications and greater economies of scale. You can increase any amount of storage and processing capacity with pay per use model.
6. High Reliability– Cloud computing makes data backup, disaster recovery and business continuity easier and less expensive, because data can be replicated at multiple redundant locations on the cloud provider’s network.
7. Security – Cloud computing gives you greater security when your hardware like laptop, mobile, tablet etc. are lost, damage or stolen this occurs as your data is stored in the cloud, you can access it no matter what happens to your machine. And you can even remotely wipe data from lost devices so it doesn’t get into the wrong hands. Cloud Ensures minimum disruption to Business.
8. Disaster Recovery – Cloud provides best DR solution for any businesses, cloud-based backup and recovery solutions save time, reduce large upfront investment due to global presence and economies of scale. Cloud service provider features like tiered storage, multiple Availability zones, Data replication etc. can be leveraged to design optimum DR and BCP solutions.

Types of Cloud Offerings

Cloud Computing services majorly  falls into three categories:

• Infrastructure as a Service (IaaS),
• Platform as a Service (PaaS)
• Software as a Service (SaaS).

IaaS – Infrastructure as a Service

Infrastructure as a service (IaaS) is a form of cloud computing that provides virtualized computing resources over the internet following pay per use model . Or we can say traditional on-prem data center services on rent for e.g. IT infrastructure—servers and virtual machines (VMs), storage, networks, operating systems.

Platform as a Service (PaaS)

Platform-as-a-service (PaaS) represents cloud services that provide platform or environment for developing, run, manage testing, delivering and managing applications on-demand online anytime. PaaS ensure ready to use development & testing platform without the complexity of building and maintaining the infrastructure. PaaS is designed to make developers and clients life easy by leveraging pre-configured systems, templates, software’s ready to build mobile or web applications  and with no hassle of setting up or managing the underlying infrastructure of servers, storage, network and databases needed for development.

Software as a Service (SaaS)

Software-as-a-service (SaaS) is a process for delivering software applications over the Internet, on demand and typically on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure and handle any maintenance, like software upgrades and security patching. Users connect to the application over the Internet, usually with a web browser on their phone, tablet or PC. To see more on SaaS, refer to Azure

Top Cloud Service Providers

As per Forbes below are the list of top 10 Cloud service providers

1. Microsoft Azure
2. AWS
3. Salesforce
4. SAP
