To become an infrastructure specialist, you typically need a bachelor's degree in computer science or a related field, along with certifications. Essential skills include expertise in network architecture, server administration, virtualization, cloud computing, and cybersecurity. Strong problem-solving and communication skills are also crucial, as is the ability to adapt to evolving technology trends and maintain an up-to-date knowledge of IT infrastructure best practices. Consider enrolling in online courses to acquire these skills.
If you are planning to get into this field, then I would suggest you enroll in this Advanced Certification in Cloud Computing from Intellipaat. This program helps you develop the required skills. Along with that have a look at this video about B Prasad and how he landed a job as an Infrastructure Specialist at IBM with a 100% salary hike just after completing course from Intellipaat.
