- 2. What is infrastructure management? □ In the context of an IT organization, infrastructure refers to the hardware, software and other systems that are necessary for delivering IT services in accordance with service-level agreements (SLAs). IT infrastructure management includes the management of IT policies and processes, along with the equipment, data, human resources and external contacts, such as vendors or security organizations, needed to ensure that IT operations run smoothly and efficiently.
- 3. What is infrastructure management? • IT infrastructure management is sometimes divided into three components: • systems management • storage management • network management. • IT organizations can also invest in cloud-based infrastructure management tools to help simplify and streamline their infrastructure management activities.
- 4. What is infrastructure management? □ Benefits of IT infrastructure management IT infrastructure management deals with the oversight of key IT infrastructure elements that are required to deliver business services. These can include software applications and networking components, but the primary focus of IT infrastructure management is typically on physical components such as computer and networking hardware and the facility itself. The benefits of good IT infrastructure management boil down to financial and operational savings.
- 5. What is infrastructure management? ❑ Improved response times to changes in operations, disasters, and other disruptive conditions. ❑ Proactive measures stemming from more agile processes. ❑ Reduced financial costs from automation and better capacity planning. ❑ Streamlined employee operations and responsibilities to create work efficiencies. ❑ Reduction in integration and system downtime.
- 6. IT infrastructure management best practices • With IT infrastructure managers being responsible for the design, implementation, maintenance and retirement of each of the above IT infrastructure elements, it’s necessary to understand the best practices for managing them. These IT infrastructure management best practices include: ❑ Knowledge gathering ❑ Creation of standards ❑ Implementation of standards ❑ Maintaining consistency ❑ Documentation
- 7. IT infrastructure management vs. IT operations: what's the difference? • IT operations management focuses on managing the daily operational tasks that are necessary to maintain the infrastructure that is used to deliver IT services. The responsibilities of IT operations control can be broken down into six basic functions: ❑ Running solutions (back-ups and configuration) ❑ Managing infrastructure ❑ Managing configurations ❑ Evolving infrastructure ❑ Mitigating disasters ❑ Governing ITOps (more commonly referred to as IT operations or ITOps) ❑ is the process of implementing, managing, delivering and supporting IT services to meet the business
- 8. Three categories of IT infrastructure management □ Our understanding of IT infrastructure management depends on knowledge of the specific components of IT infrastructure and the most important tasks associated with managing each component. IT infrastructure management is sometimes divided into three sub- categories of management: systems management, network management and storage management.
- 9. Three categories of IT infrastructure management □ Systems management • Systems management covers a wide range of key activities within the overall context of IT infrastructure management, as it includes the administration of all IT assets normally found within a data center. • A Chief Information Officer (CIO) or Chief Technical Officer (CTO) is typically responsible for overseeing the daily operations of the data center and managing the integration of new applications and third- party services into the organization's hybrid cloud environment.
- 10. Three categories of IT infrastructure management • Systems management activities include security-focused initiatives such as intrusion detection and prevention, or security information and event management. Log management workload automation, configuration management and the integration of cloud-based applications and services all fall under systems management.
- 11. Three categories of IT infrastructure management □ Network management • Network management is the discipline of managing security networks. IT security and operations analysts manage and configure networks to ensure that resources are properly allocated to applications and services where they are needed and that the quality and availability of services are maintained. Network management also includes an element of security, as IT operators must maintain visibility and transparency into the network to control the organization's security posture and protect against unauthorized access and data breaches.
- 12. Three categories of IT infrastructure management □ Storage management • Data storage space is a limited and valuable asset for IT and business organizations. Therefore, a critical aspect of IT infrastructure management is the oversight of data storage technologies and resources, such as virtualization, storage provisioning, data compression and data security. Data compression and automatic storage provisioning can reduce data times and improve the performance of the data center. processin g Automatio n reallocate and virtualization techniques can storage resources where needed. enable businesses to Other management techniques like data replication, mirroringand security help to guard against data loss or theft.
- 13. IT infrastructure management • Componenets • The main categories of IT infrastructure management, it can also be useful to understand the IT infrastructure as a composition of seven major components. IT infrastructure managers are responsible for the design, implementation, maintenance and retirement of each of these IT infrastructure elements: ❑ Computer hardware platforms Computer hardware includes client machines such as laptops and desktop computers along with server machines and mainframes.
- 14. IT infrastructure management ❑ operating systems platforms The operating systems that run on computer hardware platforms are the second component of IT infrastructure. Common operating systems include Windows, UNIX, Linux and Mac OS X. ❑ Software applications IT infrastructure management is mostly focused on managing the physical components of IT infrastructure but may exercise some oversight of the most important enterprise software applications. This typically includes applications that are critical for managing service delivery at the enterprise level, such as SAP, Oracle, Microsoft and others.
- 15. IT infrastructure management ❑ data storage components Management and oversight of data storage components is one of the key functions of IT infrastructure management. IT organizations may be responsible for managing the physical components of data storage, such as data servers, along with the software components used to organize databases (MySQL, IBM DB2, Oracle, and others). ❑ Networking and telecommunications platforms The IT organization's internal network falls under the purview of IT infrastructure management. It covers everything from virtual network software (Microsoft Windows server, Cisco, etc.) to the physical telecommunications infrastructure (telephones, routers, wiring, etc.)
- 16. IT infrastructure management ❑ Consulting and system integration services IT organizations in businesses that use legacy systems may be engaged in implementing new IT infrastructure to update legacy systems with new applications that are more powerful and robust for the modern technological setting.
