IT Infrastructure Managed Services involve outsourcing the management of core technological systems, such as servers, networks, and storage, to specialized providers, allowing companies to maintain uptime, security, and scalability without a large in-house team. This approach provides numerous benefits including cost savings, scalability, access to specialized expertise, and operational efficiency, enabling engineering teams to focus on innovation and business impact rather than maintenance tasks. Managed services can integrate with Infrastructure as a Service (IaaS) to offer flexible solutions that combine the control of IaaS with the simplicity of managed services, enhancing capabilities like real-time monitoring, automation, and observability. With tools such as PubNub, these services enable real-time alerting and messaging, supporting dynamic infrastructure adjustments and providing live insights across distributed systems. Managed services also offer specialized capabilities like predictive maintenance and security measures, ensuring optimal performance and compliance, while allowing developers to automate and integrate infrastructure controls directly into their workflows.
