Differences Between VMware vSphere, vCenter, ESXi Free vs ESXi Paid, Workstation Player & Pro

Posted in Virtualization & VM Backup

vmware esxi vsphere vcenter introIn this article we will cover the differences between VMware ESXi, vSphere and vCenter while also explain the features supported by each vSphere edition: vSphere Standard, Enterprise plus and Plantium edition. We will touch on the differences and limitations between VMware Workstation Player and VMware Workstation Pro, and also compare them with EXSi Free and EXSi Paid editions.

Finally we will demystify the role of vCenter and the additional features it provides to a VMware infrastructure.

So, without any further delay, let’s take a look at the topics covered:

Difference Between VMware vSphere & vCenter

It’s sometimes difficult to keep up to date with the latest names of software. 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:

differences between vsphere and vcenter

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:

vmware vsphere editions feature comparisonYou 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).

Netflow vs SNMP. Two Different Approaches to Network Monitoring

Posted in Netflow

netflow vs snmp introductionSNMP (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 Works

The Simple Network Management Protocol (SNMP) surfaced as early as 1988, with its roots in its predecessor, the Simple Gateway Monitoring Protocol, which was defined in 1987. 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:

Converged SASE Backbone – How Leading SASE Provider, Cato Networks, Reduced Jitter/Latency and Packet Loss by a Factor of 13!

Posted in SASE & SD-WAN Networks

sase introGlobal connectivity is top of mind for many IT teams at organizations of all sizes. We are currently in the middle of a dramatic shift in business and technology practice, as users are becoming more mobile while applications are being transitioned to the cloud.  This shift will only accelerate as companies will look to leverage the speed and agility of cloud services with the operational, cost and quality advantages of a geographically distributed work force. While Covid-19 has contributed to the acceleration of this shift, the change was always inevitable once technology was ready. Legacy connectivity and security products have long been a barrier to progress.

Topics Covered

SASE is the Answer

With uncanny timing, Gartner introduce the Secure Access Service Edge or SASE near the end of 2019, just before the Covid-19 virus started to gain global traction. SASE represents the shift away from castle & moat security with resources siloed into just a few corporate datacenters. After all, if organizations are consuming collaboration and productivity tools from the cloud, why not security and connectivity too?

While there is much buzz around SASE with security and networking vendors, and some debate over what products and services fit the SASE moniker, the intention is simple: leveraging economies of scale, organizations should purchase SASE as a cloud delivered service with global presence that brings security closer to the user. The user can be remote, mobile or in a corporate owned facility, regardless of physical location, the user’s access and security posture should remain consistent.

At Cato Networks we built the first SASE solution, starting way back in 2015. We’ve grown to 70+ Point-of-Presence (PoPs) globally that fully converge networking and security into a single platform. With our experience we believe that a global private backbone is an essential component of a true SASE solution. If we consider that the goal is consistent access and security with reduced cost and complexity, we must recognize that the ability of a user to access resources applies not just to access controls and services, but also to the usability and reliability of that user’s access. Essentially –users must have predictable performance to be productive.

A Converged Private Backbone is Essential

Reliability and predictability of connectivity isn’t a new concept or focus area for technical teams. Organizations have been using MPLS and other methods to achieve this for years. But MPLS is expensive, resulting in reliable, low bandwidth links to just a few places. Don’t forget that this approach completely neglected remote users who traditionally have had to VPN across the public Internet to reach datacenter security and resources.

Fast forwarding to today, most SASE vendors position their services as a way to reduce or eliminateMPLS, but completely ignore the unpredictability of the public Internet. Cato’s service was architected with this in mind, and we connected our PoPs with a global private backbone of multiple tier 1 providers. Our customer’s packets aren’t taking the cheapest possible route across tier 3 providers, instead taking the most efficient route to the destination. Combined with our WAN optimization capabilities, Cato ensures reliable, predictable performance for all users and locations.
