Announcing VMware HCX+ Initial Availability

If you had to sum up multi-cloud management in a single word, “complex” would be a fair choice. Although multi-cloud strategies vary from one organization to the next—i.e., some use a mix of public and private clouds while others might use only public or only private infrastructures—all multi-cloud architectures significantly increase the complexity and challenges that IT organizations must navigate.

Today, we’re excited to announce a new offering, HCX+, designed to help mitigate the challenges of thriving in a multi-cloud world. By helping to streamline and accelerate workload migration and mobility between on-premises, public cloud, and private cloud environments, HCX+ simplifies complex processes like data center modernization, hardware refresh, data center consolidation, data center evacuation, cloud migration, data center extension, cloud bursting, and cloud rebalancing.

Securing the NSX management plane against exploits

Helping organizations protect their assets and infrastructure from evolving attack tactics and techniques is a priority at VMware. API-focused ransomware attacks have become an all-too-common trend, and we recommend that customers take extra care to reduce their attack surface by deploying NSX Manager — and any other manager console — in a hardened manner.  

Management infrastructure and common services typically allow broad access to other potentially more valuable resources within an organization, which in turn provides malicious actors with convenient platforms from which they can launch more damaging attacks. To manage that risk, VMware recommends the following steps to protect your management networks and services deployed within those networks:  

  • Do not expose NSX Manager to the internet: Like any other management console, NSX Manager should be installed within your internal network and accessed remotely only through a secure VPN connection. 
  • Use strong authentication methods: Ensure that strong authentication methods, such as multi-factor authentication, are used for all NSX Manager logins. 
  • Use secure communication protocols: Use secure communication protocols, such as SSL/TLS, to protect the communication between NSX Manager and other components in the environment. 
  • Implement network segmentation: Segment the network to limit the Continue reading

Migration Coordinator with HCX – Simplified Workload Migration

With the NSX release, Migration Coordinator adds two game-changing features that help simplify workload migration in the case of lift and shift migration mode. These features build on top of the User Defined Topology mode of migration and add one more config mode. Folks familiar with the User Defined Topology will find the workflow very similar with the added benefit of simplified workload migration, leveraging HCX.   

In this blog post, we will look at this new feature and how to take advantage of it. Please check out the resource links for more information on Migration Coordinator.  We will start with a high-level overview before digging into the details. 

Migration Coordinator 

Migration Coordinator was introduced with NSX-T 2.4 to enable customers to migrate from NSX for vSphere to NSX-T Data Center. It’s a free, fully supported tool that’s built into NSX-T Data Center. Migration Coordinator is flexible with multiple options enabling multiple ways to migrate based on customer requirements. The first release provided a way to migrate everything, including config, workloads, and hosts in place using the same hardware if the deployed topology matched the supported topologies. Starting with the NSX-T 3. Continue reading

Antrea Egress on vSphere 8 with Tanzu

Welcome to this new new blog post series about Container Networking with Antrea. In this blog, we’ll take a look at the Egress feature and show how to implement it on vSphere with Tanzu.

According to the official Antrea documentation Egress is a Kubernetes Custom Resource Definition (CRD) which allows you to specify which Egress (SNAT) IP the traffic from the selected Pods to the external network should use. When a selected Pod accesses the external network, the Egress traffic will be tunneled to the Node that hosts the Egress IP if it’s different from the Node that the Pod runs on and will be SNATed to the Egress IP when leaving that Node. You can see the traffic flow in the following picture.

Antrea Egress

When the Egress IP is allocated from an externalIPPool, Antrea even provides automatic high availability; i.e. if the Node hosting the Egress IP fails, another node will be elected from the remaining Nodes selected by the nodeSelector of the externalIPPool.

Note: The standby node will not only take over the IP but also send a layer 2 advertisement (e.g. Gratuitous ARP for IPv4) to notify the other hosts and routers on the Continue reading

Network Modernization Unlocks the Power of Modern Cloud Applications  

This is a guest post from IDC Analyst Brad Casemore.

Modern applications are more distributed than ever before, deployed variously across on-premises data centers, public clouds (IaaS), private clouds, and edge locations, and sometimes delivered as SaaS. While the primacy of these data-centric applications is undeniable and will only grow with the rise of artificial intelligence (AI), a failure to ensure the modernization of underlying network infrastructure can compromise and constrain an organization’s application-driven digital strategies. 

Needs of today 

Network modernization, especially within the context of cloud-native architectures and multi-cloud strategies, cannot be an afterthought for rapidly digitizing enterprises. As applications become the powerhouse behind digital success and competitive differentiation, organizations should consider investing in software-defined network infrastructure.  

A software-defined network infrastructure provides consistent network and security policies, operational simplicity, elastic scale, and ubiquitous visibility, with support for traditional and cloud-native applications spanning on-premises environments and clouds. 

Preparing for tomorrow 

Special consideration also must be given to the future networking needs of the organization, particularly in relation to how modern network infrastructure will provide inherent portable application layer networking for cloud-native applications through functionality such as ingress controllers, service meshes, and visibility into workloads Continue reading

Enhanced NSX Edge and Networking Services in NSX

VMware NSX introduces exciting new capabilities and enhancements for virtualized networking and security for private, public, and multi-clouds. Check out the release blog for an overview of the new features.

Among these new features is NSX Gateway Stateful Active/Active Services. This feature delivers a key security enhancement, giving you the full power of the NSX Edge cluster for your services without worrying about bandwidth and CPU limitations. In this blog post, we’ll cover all the terminology you need to know for this new feature, as well as configuration and architecture, and design considerations.

Stateful Active/Active Services

Prior to VMware NSX, configuring NSX using any of the variety of NSX services offered by VMware required you to set up NSX Edge Gateways in Active/Standby High Availability mode. Under this configuration, traffic is forwarded through a single (Active) NSX Edge Node. So, when designing the architecture, you needed to be aware of the limits imposed by the Active/Standby mode on the bandwidth and CPU (Central Processing Unit) utilization of the node.

With the NSX release of NSX Stateful Active/Active Services, this consideration no longer applies. This new feature makes it Continue reading

Announcing Project Northstar: SaaS delivered Multi-Cloud Networking and Security

Multi-cloud architectures are becoming an increasingly central part of enterprise strategies delivering applications reliably. In a VMware Digital Momentum Study of enterprise technology decision-makers, nearly 73% report they are standardizing on multi-cloud foundations to operate applications and infrastructure1.

Multi-cloud infrastructure offers many benefits – such as the ability to scale quickly and increase reliability. By extension, multi-cloud deployments can help businesses:

  • Innovate and transform the customer experience
  • Scale and grow the business
  • Empower employee engagement and productivity

Yet, from an operational and technology perspective the multi-cloud presents a major challenge: Complexity. Rapid innovation and growth require the ability to deploy and manage workloads in any public cloud while providing the required service availability and scale. However, managing workloads and infrastructure on multiple clouds at once significantly increases the complexity of the network architecture connecting these applications and clouds. It also requires businesses to deploy complex security rules to protect lateral network traffic while having to rely on limited workload mobility and visibility and threat detection capabilities that do not scale.

Successfully adopting a multi-cloud infrastructure requires a means of taming the complexity that is inherent to multi-cloud.
