Explanation
Examples of serverless environments include Amazon Lambda and Azure Functions. Many PaaS offerings, such as Pivotal Cloud Foundry, also are effectively serverless even if they have not historically been marketed as such. Although serverless may appear to lack the container-specific, cloud native attribute, containers are extensively used in the underlying implementations, even if those implementations are not exposed to end users directly.

"Palo Alto Networks AutoFocus enables a proactive, prevention-based approach to network security that puts automation to work for security professionals. Threat intelligence from the service is made directly accessible in the Palo Alto Networks platform, including PAN-OS software and Panorama. AutoFocus speeds the security team's existing workflows, which allows for in-depth investigation into suspicious activity, without additional specialized resources."

Explanation
2G/2.5G: 2G connectivity remains a prevalent and viable IoT connectivity option due to the low cost of 2G modules, relatively long battery life, and large installed base of
2G sensors and M2M applications.
3G: IoT devices with 3G modules use either Wideband Code Division Multiple Access (W-CDMA) or Evolved High Speed Packet Access (HSPA+ and Advanced HSPA+) to achieve data transfer rates of 384Kbps to 168Mbps.
4G/Long-Term Evolution (LTE): 4G/LTE networks enable real-time IoT use cases, such as autonomous vehicles, with 4G LTE Advanced Pro delivering speeds in excess of
3Gbps and less than 2 milliseconds of latency.
5G: 5G cellular technology provides significant enhancements compared to 4G/LTE networks and is backed by ultra-low latency, massive connectivity and scalability for IoT devices, more efficient use of the licensed spectrum, and network slicing for application traffic prioritization.
