+# Part 1: End-to-end deployment of a sample web application on a secure VPC topology
 
-This section of the lab walks through the steps to provision a secure VPC-based topology aligned with the with Financial the **VSI on VPC landing zone** Deployable Architecture as show in the diagram below. 
+In part 1, you provision a secure VPC-based topology that is aligned with the **VSI on VPC landing zone** deployable architecture, as shown in the following diagram.
 
 ![](https://raw.githubusercontent.com/terraform-ibm-modules/terraform-ibm-landing-zone/main/reference-architectures/vsi-vsi.drawio.svg 'size=60%' )
 
-We will then manually customize the deployed infrastructure to:
-1. Expose one of the VSI in the management VPC to act as a "jump box" for operator access. This jump box is the entry point for operators to access the VSIs in the workload VPC.
-2. Deploy an Apache server in a VSI in the workload VPC.
-3. Expose the web pages served by the Apache service to the internet through a public load balancer.
 
+After you provision the VPC, you customize the deployed infrastructure in the following ways:
+- Expose one of the VSI in the management VPC to act as a "jump box" for operator access. This jump box is the entry point for operators to access the VSIs in the workload VPC.
+- Deploy an Apache server in a VSI in the workload VPC.
+- Expose the web pages that are served by the Apache server to the internet through a public load balancer.

-   This command generates two files in the current directory: `lab-key` (the private key) and `lab-key.pub` (the public key).
-   Verify that the keys have been created in the current directory.

 # Providing operator access to the VPC landing zone
 
-## Introduction

-By default, network access to the VPC landing zone topology is locked down for security compliance reasons. In this section, you will open up the necessary access for an operator to access the VPC environment, including deploying application on the VSIs located in the workload VPC.
+By default, network access to the VPC landing zone topology is locked down for security compliance reasons. In this part of the lab, you open the necessary access for an operator to access the VPC environment, including deploying application on the VSIs located in the workload VPC.

+You give operator access through the _Management VPC_. You have several options to give operator access, with varying level of security, compliance, and ease of enablement.
 
 - Exposing a VSI in the management VPC as a ‘jump-box’ by assigning a public floating IP
 - Deploying a client-to-site VPN solution in the management VPC
 - Deploying a site-to-site VPN solution in the management VPC
 - Deploying a certified bastion solution, such as Gravitational Teleport in the management VPC.
 
-This part of the lab shows how to expose one of the VSI in the management VPC as a 'jump-box', as this is one of the simplest way to proceed, albeit not being strongly secure. The [Going Further](./part1/50-going-further) section below provides links to some of the other ways to provide operator access.
+In this lab, you expose one of the VSIs in the management VPC as a 'jump-box'. This method is one of the simplest ways to proceed, although it is not overly secure. The [Going further](./part1/50-going-further) section later in the lab provides links to some of the other ways that you can provide operator access.
 
 ## Steps
 
-Perform the following actions to enable public ssh access to one of the VSI in the management VPC. This VSI will be the unique operator entry point ('jump-box') to the landing zone VPC topology.
+Complete the following steps to enable public SSH access to one of the VSI in the management VPC. This VSI is the unique operator entry point ('jump-box') to the landing zone VPC topology.
 
-1. Access the [Virtual server instances for VPC list](https://cloud.ibm.com/vpc-ext/compute/vs)
-2. Verify that the region is set to the region you provisioned your resources and click the VSI labeled _<initials>-management-server-1_
-3. Add a Floating IP address by clicking the pencil icon in the Network Interface section and reserve a new floating IP

-5. In the [Security Groups for VPC](https://cloud.ibm.com/vpc-ext/network/securityGroups), click the one labelled _&lt;initials&gt;-management_
-6. Go to the Rules section and allow port 22 for inbound by clicking **Create** in the _Inbound rules_ section (Note: Security groups are stateful so you don’t need to add a corresponding outbound rule)
