It’s a great analysis that taught me a lot about the realities of 5G, and the challenges ahead if we are to eventually get there. Our analysis suggests that the wireline paths, upper-layer protocols, computing and radio hardward architecture need to co-evolve with 5G to form an ecosystem, in order to fully unleash its potential.

Defining high availability In general terms, high availability refers to the continuous operation of a system with little to no interruption to end users in the event of hardware or software failures, power outages, or other disruptions. Database downtime can hurt or doom any company with anything to do with the internet.

AI users say that AI programming (66%) and data analysis (59%) are the most needed skills. That pricing won’t be sustainable, particularly as hardware shortages drive up the cost of building infrastructure. Data analysis showed a similar pattern: 70% total; 32% using AI, 38% experimenting with it.
