Intel Page Modification Logging (PML) is a novel hardware feature for tracking virtual machine (VM) accessed memory pages. This task is essential in today’s data centers since it allows, among others, checkpointing, live migration and working set size (WSS) estimation. Relying on the Xen hypervisor, this paper studies PML from three angles: power consumption, efficiency, and performance impact on user applications. Our findings are as follows. First, PML does not incur any power consumption overhead. Second, PML reduces by up to 10.18% both VM live migration and checkpointing time. Third, PML slightly reduces by up to 0.95% the performance degradation on applications incurred by live migration and checkpointing.

vCenter Server is the centralized platform for managing a VMware environment. It is the primary point of management for both server virtualization and vSAN and is the enabling technology for advanced capabilities such as vMotion, Distributed Resource Scheduler (DRS) and HA. vCenter scales to enterprise levels where a single vCenter can support up to 1000 hosts (VxRail nodes) and 10,000 virtual machines. vCenter supports a logical hierarchy of datacenters, clusters, and hosts, which allow resources to be segregated by use cases or lines of business and allow resources to be moved as needed dynamically. This is all done from a single interface.

Secure access service edge (SASE) is a concept initiated by analyst research firm Gartner Inc. in 2019 as part of the technology “hype cycle.” Recently, SASE has been embraced by the customer and vendor community more readily to solve a variety of modern networking and security challenges.

As they deploy 5G, telecoms operators around the world are experimenting with cloud¬native core networks, which offer greater flexibility, scalability and automation than conventional telecoms networks. This paper explores how telecoms operators could go about implementing a cloud¬native 5G core network. Most early movers are taking one of two approaches to deploy a cloud¬native 5G core:

Networking and security teams have historically relied on protections at the network perimeter to secure the entire enterprise. The internal network was deemed trusted and secure. While everything outside was considered “dirty,” everything on the internal network was considered “clean,” and application traffic would flow unrestricted. However, recent and developing shifts in enterprise working models are having a far-reaching effect on the traditionally managed network perimeter for security. The following trends are making organizations reassess their approach to security:
