A Tale of Two Migrations

Within an enterprise, there are services (systems really) that are widely popular, offer just what you need, and are easy to use. There are also systems, which for years the organization tries to decommission but they have so many applications depending on them, so many strings attached, it seems impossible. Often, it's the same system, at different points in time.

Recently while exploring a legacy application in order to design its Cloud-native replacement, we identified a connection to such a system. We will refer to this system as the SAK (aka Swiss Army Knife). We wanted to do our part and remove one more string. The SAK’s service we consume acts in essence as a proxy for a database. After investigation, we found out that our application is the only one using the specific data (and thus the service). For the data, imagine a contact list (it's not really a contact list), which facilitates the main business offering of the application. I know I am vague, but I have to be. The data in question make the main functionality easier but their lack does not make it impossible. You could still make calls without your contact list, but it would be a pain. Some clients use the application daily and some might not use it for months.

Mulesoft Dedicated Load Balancer Use Case

Introduction

We have recently implemented dedicated load balancers (DLB) into our integration landscape. I am sharing details about our use case.

Before having DLB, the VPC received all the traffic through the shared load balancer (SLB) or directly to mule internal workers through VPN. There were two limitations to this approach:

Implementing Mapping Rules With MuleSoft Dedicated Load Balancer

Introduction

Dedicated Load Balancer is an optional component within the Anypoint Platform and it is used to route the HTTP and HTTPS traffic to multiple applications deployed to CloudHub workers in the VPC.

To create a dedicated load balancer, you must first create the Anypoint VPC which can be mapped to the multiple environments and the same dedicated load balancer can be used for different environments. You can use multiple DNSs for the same dedicated load balancer (i.e. api-dev.example.com and api-test.example.com)

Security Use Cases by Industry

To understand the current and future state of the cybersecurity landscape we spoke to, and received written responses from, 50 security professionals. We asked them, "What are some use cases you’d like to highlight?"

While we covered application use cases in the previous article, here's what they told us about use cases in different industries.

Enterprise Use Cases for AWS Lambda

Last year we covered the top enterprise serverless use cases for AWS Lambda. To refresh our memory, according to the CNCF (Cloud Native Computing Foundation), AWS Lambda is most commonlyy used for REST APIs, multimedia/image processing, CRON jobs, and stream processing. Today, I’d like to cover some more complex ways some of our enterprise customers use Lambdas.  

During the AWS re:Invent back in 2017, Raghu Chandra, the Global Delivery Leader for Cognizant Technology Solutions, presented the six most popular use cases they implemented with their customers over the years. We’re going to look into three of them.

Internet of Things: A Robust Solution for Water Management Industry

The challenges for the global water industry have been countless, like population growth, migration, ecosystem pollution, water reuse, water rights, and many more. Access to water is a fundamental human right and using it in an efficient way is critical.

In recent years, the World Economic Forum Report for annual Global Risks (back in 2017) stated that environmental risks were placed before the economic risks, with water crises among the top three global risks.
