Cloud Services | AWS vs MS-Azure vs GCP

Cloud Services, AWS, Azure and GCP doesn’t need any introduction. Its well known by everyone at almost every where in the world.  As we all know about cloud services and supports, that what is Cloud, why we need, why is benefits, what is disadvantages, costing, security, flexibility, scalability etc.

What is use of Cloud

Todays with increase of computer and mobile users, data storage has become a priority in all fields, but IT companies doesn’t have enough infrastructure, equipment, servers, Storage, Security and manpower to manage.

Cloud Services is best option and solution with sufficient storage, compute and security with affordable cost.

Cloud Computing Services

• SaaS: Software as a Service
• PaaS: Platform as a Service
• IaaS: Infrastructure as a Service
• IDaaS: Identity as a Service
• NaaS: Network as a Service

Benefits of Cloud Services:

1. Lower IT Infra
2. Improved Performance
3. Less maintenance Issues and cost
4. Improve Compatibility between OS
5. Ease of Backup and recovery
6. Performance, Reliability and Scalability
7. Ease of Increase storage capacity as per requirement
8. Increase Data safety and security.

Type of cloud /Deployment Model

1. Private: Deploy for dedicated organization. Best for Intra-business, On-Premises Datacentre.
2. Public: Business to Customer, Resource Owned, Governed and Operate by Govt.
3. Hybrid: For both B2C and B2B. It’s a combination of both Private and Public.
4. Community: For Community and Organization

Cloud Computing Services

1. SaaS: Software as a Service
2. PaaS: Platform as a Service
3. IaaS: Infrastructure as a Service
4. IDaaS: Identity as a Service
5. NaaS: Network as a Service

Cloud Computing Architecture:  Cloud computing works with Front end and Back end.

Front End: Customer Dashboard

Back End: Application Server

Also, Cloud distributes the file system that spread over multiple hard disk and machine for redundancy.

Before deployment or go for Cloud services needs to consider below requirements:

1. Data Security and Privacy
2. Budget Requirement
3. Type of Cloud (Private, Public or Hybrid)
4. Client Access
5. Data backup and Restoration Requirement
6. Training Requirement
7. Dashboard Requirement
8. Data Export Requirement

Advantages and Disadvantages of Cloud Models

Public Cloud:

Advantages:

1. Cost effective
2. Reliability
3. Flexibility
4. Location Independent
5. Scalability
6. Fewer maintenance and man Power required

Disadvantage

1. Low Security
2. Shared Infra
3. Less Customizable

Private Cloud

Advantage

1. High Security
2. More Control
3. Dedicated On Premises Data centre

Disadvantage

1. Required Infrastructure
2. Required Skilled staff to manage cloud
3. Additional cost to build DR or Redundant setup
4. Extra cost for Energy and surveillance
5. Restricted Area
6. Limited Scalability
7. Extra cost for Space or Storage which is not in use.

Benefits of Cloud Services

IaaS (Infrastructure-as-a-Service)

Provide access such as

1. Physical Machine, VMs, Virtual Storage.
2. VM Disk Storage
3. VLANs
4. Load balancers
5. IP Addressing
6. Software Bundles etc.

PaaS (Platform-as-a-Service):

1. It Provide run time environment for application.
2. It also offers development & Deployment tools required to develop application.
3. Lower Administration
4. Scalable Solution
5. More Current System Software
6. No cost to procure servers and Infrastructure

PaaS has four types:

1. Stand-alone Development environment
2. Application development Only
3. Open Platform-as-a-Service
4. Add-on development facilities

SaaS (Software-as-a-Service)

• Allows to provide software application that is deployed on a hosted services and is accessible via Internet.
• Some of application is: Billing and invoice system, Helpdesk, CRM, HR portal etc.
• Software is maintained by vendors
• License may be subscription or uses based and billed on recurring basis.
• Cost efficient as not required any maintenance at end user
• Available on demand and can be Scalable as pre requirement
• Automatically upgrade and downgrade.
• Offer share data model.
• All users are running on same software version.
• Its offers efficient use of licensee.

IDaaS (Identity-as-a-Service):

When an employee access the multiple servers with same username & Password and if he left the organization, then it will be a security issue and to disable, create and maintain the new identity will increase the workload on IT staff.

IDaaS offers management of identity as a digital entity and it can be used during electronic transactions.

There are several ID services:

1. Directory Services
2. Federated Services
3. Registration
4. Authentication Services
5. Risk and event monitoring
6. SSO
7. Identity & profile management.

NaaS (Network-as-a Service): Provide network infrastructure directly and securely. User needs to log on Web Portal where he get API to use.

Cloud Computing management:  It is Cloud Provider responsibility to manage resource and their performance such as load Balancer, Storage, Backup, Capacity, Deployment etc.

Also, they manage:

1. Audit system backup
2. System’s data flow management
3. Ensuring no vendor Lock-in
4. Provide security Procedures
5. Monitoring and Audit logs
6. Solution testing and validation
7. Provide Support to users.

Cloud service providers

There are multiple Cloud Services provider includes:

• Microsoft Azure
• Amazon Web Services (AWS)
• Google Cloud Platform (GCP)
• IBM Cloud
• Oracle Cloud Infrastructure (OCI)
• Salesforce

We will discuss each of these Cloud services providers and their services Separately, but here we will get some glimpse and overview about these service providers
