WHAT IS SERVER ?

A Server is a software program or the computer on which that program runs ,that provides a specific kind of service to client software running on the same computer or other computers on a network.

SERVER DESIGN PRINCIPLES →R: RELIABILITY

→A:AVAILABILITY

→S:SCALABILITY

→ U:USABILITY

→ M:MANAGEABILITY

Server management

WHAT IS STORAGEStorage is a process or storing data onto media in a proper,Secure, and effective manner and ensures that stored data Accessible

RAID (Redundant array of independent disk)

RAID 0 DATA STRIPING WITHOUT PARITY

RAID 1 DATA MIRROR WHITHOUT PARITY

RAID 3 DATA STRIPING WITH PAROTY INFORMATION STORRED ON A DEDICATED HARD DISK

RAID 5 DATA STRUPING WITH PARITY INFORMATION DISTRIBUTED ACROSS ALL HARD DISKS

RAID 6 DATA STRUPING WITH PARITY INFORMATION DISTRIBUTED ACROSS ALL HARD DISKSAS WELL AS STORED ON A SEPARATE HARD DISK FOR EXTRA BACKUP

RAID 0+1 PERFORM RAID 0 AND RAID 1 I ORDER

RAID 1+0 PERFORM RAID 1 AND RAID 0 IN ORDER

RAID 50 PERFORM RAID 5 AND RAID 0 IN ORDER

Cloud computing

CONCEPTCloud computing refers to the delivery of computing as a service rather then a product , whereby shared resources, software , and information are provided to computers and other devices as a utility over the network (internet).

In a narrow sense , cloud computing refers to the delivery and usage models of it infrastructure.

In a broad sense, cloud computing refers to the delivery and usage modules of services.That is , IT software and internet services are delivered on demand over the internet.

Characteristics of a Cloud Environment• Self-service - As a user, you can use the

service as you require

• Per-usage based pricing model - You

should only ever pay for the amount of

service you consume

• IP-based architecture - Cloud architectures

are based on virtualised, internet based

technologies

DEPLOYMENT MODELSPublic cloud:-Available to the general public or large

industry group and is owned by an organisation selling cloud services

Private cloud:-– Operated solely for an organisation or company

Hybrid cloud:-Combination of two of the above, they remain unique entities but are bound

together by standardised technologies

Community cloudShared by several organisations and supports a specific community that has

shared concerns

SERVICE MODELSIaas : infrastructure as a service ( cloud providers offer infrastructure resources including software and hardware resources Users can use these infrastructure over the internet and deploy applications on them)

Paas : platform as a service (cloud providers deliver a computing platform , on which application developers can develop new application or expand the existing application)

Saas : software as a service (cloud providers install application software in the cloud . Users can access these applications over the internet)

TYPES OF CLOUD COMPUTING1. Private cloud – enterprise owned or leased

2. Public cloud- sold to the public

3. Hybrid cloud - composition of two or more cloud

These services are broadly divided into three categories

1. Cloud software as a service(Saas)- use providers application over a network

2. Cloud platform as a service(Paas)- deploy customer created application to a cloud

3. Cloud infrastructure as a service(Iaas)- rent processing

CLOUD COMPUTING ADVANTAGES

→Agility:-improves with users ability to re-provision technological infrastructure resources.

→Application programming interface(API):-accessibility to software that enables machines to interact with cloud software

→Device and Location independence.

→Security
