Companies in all industries are responding to new opportunities to leverage big data and mobility to improve service and increase productivity. For IT teams, the switch to digitally driven business has big implications.

Lifecycle management from deployment to maintenance
The Universal Distributed Logical Router is installed in the kernel of every ESXi host, as such it requires a VM to provide the control plane.
The universal distributed logical router Control VM is the control plane component of the routing process, providing communication between NSX Manager and NSX Controller cluster through the User World Agent.
NSX Manager sends logical interface information to the Control VM and NSX Controller cluster, and the Control VM sends routing updates to the NSX Controller cluster.

Container technology can help transform a company into a digital enterprise focused on delivering innovations at the speed of business. Containers package applications and their dependencies into a distributable image that can run almost anywhere, streamlining the development and deployment of software.
By adopting containers, organizations can take a vital step toward remaking themselves into flexible, agile digital enterprises capable of accelerating the delivery of innovative products, services, and customer experiences. Enterprises can become the disrupters instead of the disrupted.
But containers create technology management problems of their own, especially when containerized applications need to be deployed and managed at scale, and that’s when Kubernetes comes into play.
Kubernetes automates the deployment and management of containerized applications. More specifically, Kubernetes orchestrates containerized applications to manage and automate resource utilization, failure handling, availability, configuration, desired state, and scalability.
This book introduces you to containers and Kubernetes, explains their business value, explores their use cases, and illuminates how they can accelerate your organization’s digital transformation.
Context- aware firewall enhances the visibility at the application level and helps to override the problem of application permeability. Visibility at the application layer helps you to monitor the workloads better from a resource, compliance, and security point of view.
Firewall rules cannot consume application IDs. Context-aware firewall identifies applications and enforces a micro-segmentation for EAST-WEST traffic, independent of the port that the application uses. Context-aware or application-based firewall rules can be defined by defining Layer 7 service objects.
After defining Layer 7 service objects in rules, you can define rules with specific protocol, ports, and their application definition. Rule definition can be based on more than 5-tuples. You can also use Application Rule Manager to create context-aware firewall rules.
Firewall can take action based on one or a combination of different L2, L3, L4, and L7 packet headers that are added to the data as it moves through each layer of the TCP/IP model.
In layer 3 or layer 4 firewall, the action is taken solely based on source/destination IP, port, and protocol. The activity of network connections is also tracked. This type of firewall is known as a stateful firewall.
Layer 7 firewall is also called as a context-aware firewall. Layer 7 or context-aware firewall can do everything that the layer 3 and layer 4 firewall do. Also, it can intelligently inspect the content of the packets. For example, a layer 7 firewall rule can be written to deny all HTTP requests from a specific IP address.
If your dashboard is indicating that a host is not in a healthy state, you can capture packets for that particular host for further troubleshooting. You can capture packets using the new Packet Capture tool, to help diagnose and solve network related problems.
You can create a packet capture session for required hosts on the NSX Manager using the Packet Capture tool. After the packets are captured, the file is available to download.
Maximum of 16 sessions and total of 400 MB files are available to download. If you want to start a new session after reaching maximum session, you must clean the older sessions.
Your session remains active for 10 minutes, and the existing session is removed one hour after the session was created. If you restart NSX, all the existing sessions are cleared.
VMware vSphere 6.7 delivers key capabilities to enable IT organizations to address the following notable trends that are putting new demands on their IT infrastructure:
Explosive growth in quantity and variety of applications, from business-critical applications to new intelligent workloads
Rapid increase in hybrid cloud environments and use cases
Global expansion of on-premises data centers, including at the edge
Heightened importance of security relating to infrastructure and applications
Harald Ruppert, a vSAN Escalation Engineer at VMware has created a great tool to check if your vSAN harware is supported. The vSAN HCL viewer is based on the VMware vSAN HCL in JSON format for online use of vSAN health checks.
If you would like to build your own vSAN, then you can do so using certified components, and you must confirm that all your components including drives are supported by the OEM server vendor and VMware. Simply select the type of component; SSD, HDD or controller and put in a partial Model or Vender and the result shows immediately.
This document covers how one can create security policy rules in VMware NSX. This will cover the different options of configuring security rules either through the Distributed Firewall or via the Service Composer User Interface. It will cover all the unique options NSX offers to create dynamic policies based on the infrastructure context.
