Transform Pub/Sub to Firestore Database in GCP
This year, the client I work with has started exploring the offerings in Google Cloud Platform (GCP) after investing years into the Microsoft Azure cloud. The opportunity has allowed me to explore a few new technologies that this post will cover and that you will hopefully find interesting.
In short, I was tasked with transforming Pub/Sub to Firestore Database in GCP. The scenario explored in this post takes an FHIR healthcare data feed, extracts telephone and email information, and then stores that in a Firestore database.
The Jury is Still Out: Blockchain in Healthcare
Blockchain has gotten the software world buzzing about its potential applications in different business areas. With the US spending 17.9% of its GDP on healthcare in 2017 per CMS, many companies are considering how to enter into a market that has such potential for growth as well as the potential to positively affect patient’s lives.
Keyhole Software stays ahead of the curve by investigating new trends in software so that when clients come to us asking for advice we can provide an informed opinion. We do not want our clients to be guinea pigs, and we help provide guidance so that the solution they choose is the best one regardless of the trends of the day.
Blockchain is something we feel could be a good fit for the right use case, which we’ve elaborated on in our Blockchain Case Study. It is, at the end of the day, just a tool, and should only be used when it is beneficial to do so. Healthcare is an incredibly complex industry, so it is important to understand what Blockchain is, what it is not, and what needs to be considered before using the technology.
The purpose of this blog post is to think through how Blockchain can be applied to healthcare software applications. This blog post does not dive into the technical implementation of Blockchain, only its application in healthcare. A technical deep dive into Blockchain can be found in our Blockchain White Paper.
