VMware NSX Reviews

NSX is used with vCloud Director to provide networking as a service or extend the capabilities of the load balancer, VPN, firewall, etc. There are two types of NSX. VMware's latest version is a product called NSX-T. It's a universal solution used across the VMware lineup and products like Hyper-V or the public cloud. You can use it on-prem or public cloud as well. NSX is used by the operations team, architects, and engineers. There are maybe 20 to 30 people using it.

NSX extends Layer-2 scalability on Layer 3, covering the vRO and extending the capability on Layer 3 by decapsulating using a new mechanism. NSX-V was designed to use with VMware products and Success 360, providing more flexibility toward different levels of cloud, containers, and components. NSX-T gives you the ability to stretch your network across different view locations. If you have multiple sites, you can connect them using NSX-T.

In the next release, they should enhance the visual interface. With NSX-T, it's difficult to communicate between the public cloud and the container. 

I have been using NSX for three or four years. 

NSX is stable.

NSX is scalable. You can deploy it on one node or a three-node cluster.

I rate VMware support six out of 10 for NSX-V and seven out of 10 for NSX-T.

Deploying NSX is difficult. VMware NSX has three components: management, controller, and database. You have to understand each of them and where to deploy them. There are lots of logs as well. The deployment varies whether you are deploying on a VM, public cloud, or standalone hardware. Each has its own prerequisites.

First, you have to enable features on your physical equipment, enabling you to install NSX. You have to deploy the dependencies and fix the board. The deployment time depends on the equipment, whether it's from Cisco, Jupiter, or another vendor. They have different approaches to enabling NSX.

The licensing is based on the CPU or the physical unit.

I rate NSX nine out of10. 

We use VMware NSX for application service deployments.

VMware NSX is a very good solution. It's also a scalable solution.

It could be more user-friendly, but it's manageable. When we add a specific node to this particular NSX and the configuration changes, it won't push through the errors where required, but it'll accept it. However, while using it, we will have issues. It can also be more stable. 

It could be more stable.

VMware NSX is a scalable solution. We have about 10,000 people using it at our company.

Technical support is good.

We are still in the process of completing the migration from the physical servers to NSX.

The initial setup is relatively straightforward, but it takes a long time to implement this solution. You need hundreds of people to deploy and maintain this solution.

VMware NSX isn't cheap. 

I would tell potential users that they need to do a high-level review of their entire data center architecture, and should not leave any specific configurations related to connectivity that would lead them to more challenges. 

On a scale from one to ten, I would give VMware NSX a seven.

Our primary focus is to create a layer that effectively connects to the remote site. This involves optimizing and accelerating the VXLend component, which is highly popular in our setup. We usually configure VXLend to enhance disaster recovery capabilities, specifically for applications that operate within the same subnet. This approach ensures that in the event of a disaster, such as a WAN failure or when external layers are inaccessible, there's no need to change IP addresses. It allows users to connect seamlessly from any location since the servers maintain the same subnet, and data replication occurs between the data centers. The result is minimal disruption and no requirement to modify configurations during these critical scenarios.

Traditional network management often involves dealing with individual components separately while VMware NSX offers a more streamlined approach. It operates on a logical level, providing a comprehensive and centralized way to manage your network resources. This not only simplifies management but also enhances scalability. It enables us to create and adjust policies dynamically, allowing for real-time updates and enforcement so we can effectively oversee our entire data center from a single point of control.

One aspect that needs improvement is the need for further automation. We are already operating in a software-defined data center environment, and while the product is mature, there's room for enhancing automation.

I have been using it for approximately three years.

It provides robust stability features. I would rate it nine out of ten.

It provides excellent scalability capabilities. When it comes to micro-segmentation, it allows you to scale naturally. You can distribute firewall and load-balancing functionalities efficiently as your network grows. It also offers seamless integration with the physical network infrastructure, making it easy to extend your virtualized network into the physical world.

The customer support from VMware is exceptional. Recently we encountered a critical issue where one of our virtual machines failed to start and was displaying a blue screen. Despite the urgency of the situation, we logged a support case, and within twenty minutes, we received a response. A support representative promptly called us, established a remote connection, conducted a thorough analysis, and successfully resolved the problem.

Positive

I have experience with Cisco, but I find VMware to be a superior solution. The primary reason is the seamless integration that VMware offers, especially within a data center environment. When working within a data center, VMware's virtualization capabilities are all that we need. We no longer require separate hardware, edge products, load-balancing solutions, or firewall products. Everything can be fully integrated into a unified system and it allows us to accomplish everything from one console and one central point of control, making it a highly efficient and streamlined solution.

When it comes to VMware, there are two primary options: NSX-V and NSX-T. NSX-V is known for its user-friendliness and effectiveness. Setting up SD-WAN connectivity with NSX-V is straightforward.

The price is significantly high and it can be a hurdle for many potential users.

I would highly recommend VMware for a wide range of users, spanning from large enterprises to small and medium-sized businesses. It's an ideal choice for those who require disaster recovery solutions or cloud extensions. Its versatility and capabilities make it a valuable choice for anyone looking to scale their infrastructure, whether it's within a data center or by extending into the cloud. I would rate it eight out of ten.

We're moving towards hyper-converged solutions with VMware, including NSX and vSAN. This direction has promising prospects in the market.

One significant advantage of VMware NSX is the ability to provide advanced security at the micro-level, focusing on securing applications and workloads rather than just the network structure or virtualization-based network security.   

I believe we need to attain a certain level of maturity and work closely with multiple customers to make substantial improvements and achieve notable results. The feature it can improve is essentially application-based load balancing with intelligent load distribution for applications that require redundancy and high availability. This feature operates at a micro-level, specifically focusing on the payloads of applications.

To clarify further, I believe that if NSX offers this functionality along with robust security measures for application payloads, it would greatly benefit customers. Instead of investing in additional devices or appliances for load balancing and security, organizations would likely prefer to leverage NSX's integrated capabilities in this regard.

We have been using this solution for the past six months. 

As for stability, the customer I mentioned earlier is extremely satisfied with the product's stability.

VMware doesn't have a physical presence in Pakistan. They recently initiated their operations here. However, we do have interactions with their team based in Singapore, and I must say they are quite supportive. The customer hasn't raised any complaints regarding their support. The time required for deployment can vary based on the size of the infrastructure, but typically, it can be accomplished within a two-week timeframe.

Positive

One of our prominent clients is a major university in Pakistan, and they expressed dissatisfaction with their current solution, Sentra for SCI. They expressed a desire to transition to VMware, specifically NSX, as they are seeking hyper-converged integrations with both cloud and on-premises solutions.

Regarding the initial setup, VMware products, including NSX, are generally straightforward to set up and deploy, so complexity hasn't been an issue.

The implementation of VMware NSX can be cost-intensive, especially if an organization is looking for a comprehensive solution. The costs can vary based on factors like the level of conversation and discounts obtained during negotiations. Some government organizations, for instance, may find the prices relatively high, leading to concerns about budget hikes, especially when deploying the solution across the entire organization.

Regarding maintenance and support, they are typically included in the standard licensing costs for enterprise-level businesses. While these costs can be significant, many companies opt for standard licensing to ensure they have access to necessary support and maintenance services.

The deployment of NSX security can be somewhat challenging, and it requires a thorough understanding of the organization's specific needs and objectives. To effectively implement NSX security measures, it's crucial to have a clear understanding of the applications, payloads, and various components within the network environment.

The solution's most valuable feature is ease of use. Its filtering features work best for our business requirements.

It could be helpful if the solution's licensing model is based on the number of VMs rather than hypervisors.

We have been using the solution for seven years.

It is a stable solution. I rate its stability as an eight.

The solution's scalability depends on the licensing model.

The solution's customer service is good.

The solution is reasonable at the local level. But it is expensive to deploy it globally.

I advise others to understand their business requirements. They should know if they want the solution to block some protocols or to make accurate filtering. I rate the solution as an eight.

Our clients are moving from traditional to virtual infrastructure, so we sold them vSphere, vSAM, and NSX to manage all the workloads inside VMware. All the VMs work just like traditional infrastructure inside an appliance.

NSX has excellent security features like virtual firewalls. I also like the micro-segmentation features, which are useful for the virtual machines inside the servers.

I started working with Nutanix NSX last year. 

I rate NSX eight out of 10 for stability. 

NSX is easy to scale. 

We sell Nutanix, Dell EMC, HPE, and IBM. Right now, I'm working with IBM Storage and Power Servers. We have Pure Systems, too, but I'm still new. It's my first week at the company, so I'm still studying other vendors that I'm unfamiliar with.

I'm not implementing. I am selling the solution. You can use it on-prem or in the cloud. If you are using SRM, including NSX in your workloads makes things easier. You can easily move everything, including the network security and several layers inside the appliance, to the cloud or any other site.

VMware has a subscription and perpetual license. In the New Year, they're changing many things about the licensing model. Previously, NSX was licensed according to the number of sockets inside the appliance, so we bought VMware licenses based on that. However, that may have changed this year. We are still contacting the vendors to understand the new licensing strategy.

I rate VMware NSX nine out of 10. I recommend it.

We were using VMware NSX for high availability. 

We recently used it to migrate a way to the public cloud.

The migration methods are the most valuable aspect of this solution. The rest is just overly complicated.

We had some issues with the cloud version.

It needs to be cheaper.

We are stopping its use. We won't need it because we'll be using cloud-native.

The company has been working with VMware NSX for six years.

I have hands-on experience with VMware NSX.

It was on-premise, but we just used it to do cloud migration to VMC, and it will be removed after that.

The on-premises version of VMware NSX was not stable, but it was for VMC migrations. 

The on-premises version of VMware NSX is not scalable.

The cloud version is most likely fine. I couldn't really say, but after the on-premise system was implemented, everyone was afraid of change. It was really flaky.

We don't have a large number of users. It is not used as such by people; it is a piece of infrastructure software.

There would have been less than half a dozen, not very many.

I personally have not had any contact with technical support.

The initial setup is complex.

TCS assisted us with the installation.

If five is a good price and one is a high price, I would rate the price a one out of five.

I would not recommend this solution to others.

As a technical solution, I would rate VMware NSX a five out of ten.

I used to sell the solution as a bundled package. My role was to find the best solutions for customers from various vendors and work with our pre-sales and solution architecture departments to present these options. I provided high-level advice and my colleagues provided technical details. 

Our customers used the solution for segmentation and automation to secure workloads in their lower computing layer. One customer was CaixaBank, an important financial institution in Spain. 

The dashboard is comprehensive and easy to use. 

The solution integrates perfectly with F5, Check Point, and other applications. Integration with vendors is very important for customers. For our CaixaBank deployment, the solution performed these integrations which included defining, automating, and applying different rules and security functionalities. 

The solution is only sold as part of a bundle and not as an individual product. Some customers only need vSphere or NSX for their use cases, but account executives focus on bundles so this is a problem. 

Account executives need to talk with both systems and security staff to get a full picture of the environment's requirements. For example, systems staff have no need for the solution so they will never deploy it. 

I have been familiar with the solution for three years. 

The solution is very stable. 

The solution is scalable and can handle deployment to thousands of devices with no issues. 

Technical support is very, very good. Staff work hard to understand new functionalities or bug fixes that are released monthly. 

The setup depends on the project scope. For example, CaixaBank's project had a very large scope that was divided into many different parts. Deployment took one year but the project is still ongoing. 

Good deployments depend on an assessment phase where you talk with different departments before defining objectives. Discussions should occur both with systems and security staff. With proper pre-assessment, the solution operates and integrates perfectly. 

The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle. 

Customers do not know the individual price of the solution so they compare the package pricing to competitors. The solution should offer stand-alone pricing so it can be accurately compared to other options. 

There are many solutions in the market that offer similar functionality and characteristics. 

Palo Alto, Fortinet, and Cisco offer lower prices because they are considered legacy. Segmentation is very detailed so many customers prefer legacy options for peace of mind. 

The solution is a very, very good product that is perfect for customers who have good technical support. 

I recommend the solution and rate it a seven out of ten.
