Even the largest technology vendors change their product names from time to time. Unfortunately, getting the product name wrong can result in various costly consequences including purchasing the wrong product or an older version with differentiating feature sets.Contrary to popular belief, vSphere and vCenter are actually different products:vSphere is VMware’s name for a suite of Infrastructure products. You can think of it as a platform name which includes lots of different components.vCenter is the name of one of the components under the vSphere suite. vCenter runs on a Windows Server VM and provides the management and control plane of the entire VMware environment. This is also shown in the diagram below:Looking at the vSphere suite, the components and features that vSphere includes depend on your licenses. vCenter Server is available on all vSphere editions.Here is an overview of some features for the main vSphere editions:You will notice that this vSphere feature table contains many different technologies which are found in different VMware software components.vCenter is a management tool that helps manage multiple ESXi / vSphere Hypervisors within the datacentre. Earlier versions of vCenter (also known as vCenter Server) ran exclusively on Windows Server (shown in the previous diagram) whereas now VMware now offers the vCenter Server Appliance (vCSA) which runs on either SUSE Linux Enterprise Server 64-bit (vCSA v6.0) or VMware’s proprietary Photon OS (vCSA v6.5 and above).You log in to vCenter Server via an HTML5 browser (formally a Flash client) which looks like this:Continue ReadingFree Webinar: Clients' network configuration and compliance managementPosted in OpManager - Network Monitoring & ManagementDefending your client's network from faulty configuration changes, poor compliance, and bringing the network back quickly from downtime can be challenging.

Two Different Approaches to Network MonitoringPosted in NetflowSNMP (Simple Network Management Protocol) and Netflow are both popular protocols with admins, prized for their ability to give visibility over the network and in some cases discern the cause of network performance issues, network bottlenecks, system resource allocation issues and more. On the Netflow side of things, third-party software vendors like ManageEngine can greatly enhance the usability and capability of the protocol, while SNMP network monitoring applications like PRTG, Solarwinds or alternatively open-source Observium, Nagios and LibreNMS take the lead in delivering a comprehensive in-depth network and system monitoring solution.Unfortunately, however, the close relationship between the two protocols, especially when it comes to software offerings, has birthed some misconceptions. While it’s common to see SNMP and Netflow as more or less interchangeable, there are some significant and key differences between the two that make them suited for very different use cases.Let’s take a quick look at what we’ve got covered in this article:Understanding SNMP and how it worksUnderstanding Netflow and how it worksNetflow vs SNMP: Similarities and differences, using real examplesNetflow vs SNMP: Advantages and disadvantages, using real examplesNetflow vs SNMP - ConclusionRelated articles:Complete Guide to Netflow: How Netflow & its Components Work.

SNMP was born out of pure necessity – before its existence, network admins didn’t have much visibility over their infrastructure at all. After the crash of the ARPAnet, on the 27th of October 1980, and as the number of complex components in networks began to snowball, it was clear a solution was needed.However, though SNMP was initially built by a group on university researchers as a temporary solution, it quickly evolved, has remained very relevant even today. It’s not considered part of the application layer of the Internet Protocol Suite and OSI model and exists across three major versions (through SNMPv1 still tends to be the most commonly used).Though SNMP’s name suggests management, it’s more commonly used for the monitoring of different types of network equipment, both on a network and hardware level. Typically, a monitoring server (e.g Nagios, Observium) known as a SNMP Manager monitors devices on the network, with each system holding a software snmp agent that reports information back to the manager:Illustrating how SNMP worksContinue ReadingFree Webinar: Enterprise-Grade Security and Management for Samsung Mobiles, Tablets, Smartwatches and other DevicesPosted in OpManager - Network Monitoring & ManagementThe hybrid work culture has resulted in workforces increasingly using their mobile devices for work, further adding to the complexity of ensuring security across all endpoints within organizations.The majority of IT professionals believe that mobile devices are just as vulnerable to security threats as any other endpoint, making it crucial to bring them under the umbrella of management and have the requisite security measures applied.Tune in to this joint webinar by ManageEngine and Samsung to learn how you can apply enterprise-grade security on all your Knox capable devices, and centrally manage endpoints from one single console.Highlights of this webinar:Samsung Knox and its benefits.Leveraging ManageEngine's partnership with Samsung for advanced device management and security.Managing devices in remote work and frontline worker scenarios.Uncovering the bigger picture: UEM for all-inclusive device management.A live Q&A session with experts from ManageEngine and Samsung.Tune in to this webinar on: 23 March 2022 at 11 AM EDT | 24 March 2022 at 12 PM ISTClick here to claim your spot nowContinue ReadingMore Articles ...Converged SASE Backbone – How Leading SASE Provider, Cato Networks, Reduced Jitter/Latency and Packet Loss by a Factor of 13!Configuring A SASE Unified Network: Data centers, Remote Sites, VPN Users, and moreRenewing Cisco Certifications without sitting for a Cisco Exam.
