React Native is one of the most popular frameworks used in mobile development. It was created by Facebook based on Javascript. It can be used to build apps to iOS or Android with native platform capabilities.

Expo is a tool that helps you speed up development time and testing.

This article explains how you can integrate a React Native app with Back4App. After completing this step-by-step tutorial, you will have built a project to manipulate a To-Do List.

Is it your first time using Back4App? If so, you need to do the Sign-Up.

When faced with the challenge to migrate from RDBMS to NoSQL, specifically MySQL to MongoDB, many programmers and/or people who don’t have deep experience with Databases end up cornered between expensive commercial ETL tools or free community tools.

Usually the latter is the option of choice for its obvious pricing advantage and, while MongoDB has a great import tool (a.k.a. mongoimport) which can successfully import CSV and JSON files, that can be easily generated with MySQL, a few times the complexity of the Database structure makes this process quite challenging, as conversion of values might not always match for both databases.

This article is intended to give you another option to help developers with migrating such data.

Price to self-host a Parse app on AWS

Would you like to know how much it costs to run your Parse app directly at AWS? So, you are in the right place and we will provide the prices for hosting a Parse app at AWS. We will calculate the costs based on two different scenarios. The first scenario will cover a small application and will not provide a redundant infrastructure. So, if any of the instances fail, the app will face downtime. The second scenario will cover a more robust structure with redundant application instances and a replica set to run the databases.

Small Parse App – Infrastructure without redundancies

The minimum setup we suggest is two small instances. One instance to deploy the database and one instance to run the application server.

We recommend choosing new generation instances like t3 to deploy your app. The on-demand cost for each t3.small instance is $15.23/mo. So, having two instances will cost you $30.46/month. On top of that, you still will be required to pay EBS costs and data transfer. Let’s consider 30GB EBS for each instance and 250GB monthly data transfer.

The total cost will be as follows:

Application Server: $15.23

Database Server: $15.23

EBS: $6.00

Transfer Out: $22.41

Total: $58.87

Free Tier Discount (for new users only): $4.26

Total with discount: $54.61

Small Parse App – Redundant Infrastructure

The minimum setups we recommend are 4 small instances and 1 nano instance. Two small instances will cover the application servers, two instances will form a replica set for the database and the nano instance will act as an arbiter. The structure will look like this:

Parse self-hosted apps

So, having five instances will cost you $64.73/month. On top of that, you still will be required to pay EBS costs and data transfer. Let’s consider 30GB EBS for each instance and 250GB monthly data transfer.

The price is detailed as follows:

Application Server: $30.46

Replica Set: $30.46

Arbiter: $3.81

EBS: $15.00

Transfer Out: $22.41

Total: $102.14

Free Tier Discount (for new users only): $4.26

Total with discount: $97.88

Back4App

If you are planning to host a Parse app, you should consider Back4App. We have long term contracts with AWS and volume discounts. So, we can provide very affordable Parse managed services at a lower cost in comparison to directly hosting at AWS. Unless your app has huge workloads, you won’t be able to beat our pricing. Our plans start at $5/month, and all plans provide a fully redundant and scalable structure. There is no lock-in, you keep your data and we offer add-ons like the multitenant dashboard, collaboration tools, advanced security, and database optimization. Please see all the benefits of Back4App reading the article below.

Self-Hosted Parse vs. Back4App

If you still want to host your app with AWS, we offer self-hosted professional services. To know more, please fill the form below (it takes only 2 minutes) and we will send more information to you.

Professional Services

Back4App is a heavy Amazon Web Services user and we run most of our infrastructure on this cloud provider. We will show you how we delivered $500,000 in yearly Amazon Web Services savings. Software development companies, startups, and enterprises can benefit from this article because:

• It provides effective and proved ways to reduce AWS spending;
• We show how to have short-term and low hanging fruit gains;
• Most of the procedures are simple and demand only planning and hard work.

The actions described in this article are based on our own experience managing cloud infrastructure and translated in successful cost reductions. Here is a brief checklist of what you will find reading this report.

As you have probably heard, the Buddy.com platform is turning off its Parse hosting service. We are glad to offer our assistance to help Buddy users to migrate to Back4App. We’ve developed a CLI Migration tool especially for migrating Parse Apps to Back4App. The tool is so straightforward that it can help Buddy users to migrate their apps in minutes. In this post, I describe in detail how to use this CLI Migration tool to move your database and files from Buddy. Also, I suggest an approach to migrate other features such as cloud code and integrations.

When you key in ‘How to Clone Apps’ on the internet, a bucket of resources, blog posts, whitepapers, articles, and video tutorials can be discovered on SERPs.

As a developer, at some time, you might have worked in a team that utilizes a shared database for development, User Acceptance Testing (UAT) or deployment. If so, you must also be familiar with many overlaps between projects, contentions for resources, erratic environment stages, and high-level of dependency on other team members to get the end product deployed.
