IT Infrastructure: Cloud Computing, Components, Roles & Security

This report provides an overview of IT infrastructure, detailing its components such as hardware and operating system platforms, enterprise software, data management and storage, networking, and internet platforms. It explores the use of cloud computing and virtualization in scaling web applications, highlighting the roles and responsibilities of an IT infrastructure manager, including staff management, vendor relations, and strategy development. The report also addresses security issues associated with using cloud infrastructure, such as DDoS attacks, shared services vulnerabilities, data loss, employee mistakes, and phishing attempts. References to external sources are provided to support the information presented.

IT INFRASTRUCTURE
Components used for IT Infrastructure
IT Infrastructure using Cloud computing and Virtualisation
 Hardware platforms: It includes client machines and server machines.
 Operating system platforms: Platforms for client computers where either platforms like UNIX or
platforms like windows are used
 Enterprise and other software application: Consists of middleware software, Oracle, PeopleSoft
and SAP.
 Data management and storage: It comprises of traditional storage methods (disk arrays and tape
libraries) and newer network-based storage technologies like storage area networks (SANs).
 Networking and telecommunication platform: Novell, Windows server operating systems, UNIX
and Linux and utilises TCP/IP protocol for data transmission.
 Internet platforms: Internet infrastructure involves services, hardware and software to manage
corporate Web sites, intranets, and extranets, consisting of Web hosting services and Web soft-
ware application development tools.
 Consulting and system integration services : It consist of legacy system having new technology
and infrastructure as well as helps in making changes in business processes, training, and soft-
ware integration .
Architecture to Scale Web Applications in a Cloud Security issues in using Cloud as an IT infrastructure solution
 Distributed-Denial-of-Service Attacks.
 Shared Cloud Computing Services.
 Data Loss and Inadequate Data Backups
 Mistakes of Employee can lead to giving
easy access to hackers.
 Phishing and Social Engineering Attacks
 System Vulnerabilities
Role and responsibility of an IT infrastructure manager
 Staff Management as well as he should be able to networking, physical cabling
and server management
 They have the responsibility to make strong relationships with the vendors to
ensure best IT infrastructure is maintained.
 Establishing standards and procedures for managing and working in this IT
infrastructure.
 Strategy making for IT management.
 Monitoring and reporting about any challenges faced in IT infrastructure
 Ensuring that right tools and software are placed to manage the infrastructure.
