I have a spring application based on Spring 3.0 for rest web services.I was planning to deploy it to heroku but facing a lot of issues.Can someone tell me some free hosting or even paid hosting where i could deploy my application?
Forgive me for my inexperience at server side
Thanks
Cloudbees is a great PaaS product that offers you a Tomcat/MySQL infrastructure for your applications. I've tried the free version and I had no problems at all.
The other popular choice is go with Amazon Elastic Beanstalk, but I haven't used it yet (mainly because of the price). A nice comparison between popular PaaS products can be found in this DeveloperWorks article.

I am using Java spring boot for an REST API, using Stripe to handle Payment. To handle the payments, I am planning to use an Express server. Is this Okay? Will I face any issues in deployment?
I am planning to start working on it soon.
This is really an architectural choice that you can take. It can be justified as being part of a micro-services architecture. This is not uncommon, to have different services being developed with different languages and infrastructures, especially when you have different teams with different skillsets working on isolated features/services. There are a couple of things to be careful about though:
Maintainability
Interoperability
Infrastructure
Security
etc.
I hope this gives you enough to think about to make your decision.
I am looking for sample RESTFull application, that can be deployed in Webpshere Application Server 9.x. Posting here with great hope after exhaustive search. Any help much appreciated
There are many samples, here you have two, they are for WebSphere Liberty, but the main concepts and code is the same:
OpenLiberty /sample-restful-webservice
Creating a RESTful web service
There is no need to use Jersey, just use JAX-RS api provided by container.
We are developing our application which probably is going to consist of about 20 Microservices. We are considering to use Pivotal Cloud Foundry to manage our Microservices and make it easier to have a platform for deployment and health check - amoung others.
About 12 Microservice will render HTML and now we want to know how we can compose all these services to one UI and present it to the client. Does Cloud Foundry a plugin or somehow solves the UI issues for Microservices? Does PCF generates Composite UI?

No, the platform does not do this for you. It only handles routing requests to your apps.

You might look into using a proxy app in front of your microservices. The proxy would just be responsible for presenting a unified front for your clients and combining all the backend services together.
Netflix Zuul/Spring Cloud Zuul or Spring Cloud Gateway might help with this, if you're using Java. I've also see people use Nginx as a reverse proxy to do similar things.
At the end of the day, you're going to need to figure out what works for your particular microservices & clients side apps though. I don't think anyone can give you a definitive answer to your question, at least not without a lot more information.
I'm looking for open source applications that demonstrate the microservices pattern. In particular, I'd like to find one or more applications that can be spun up on real cloud environment up (but with fake data and requests) to demonstrate real-world deployment mechanics.
Unfortunately, I haven't found any good options yet. I'll note that Discourse is a modern 3-tier application, using Rails API, Ember.js, Postgres, and Redis, but it still is much closer to a monolith than an example of microservices. The closest I've found so far is https://github.com/kbastani/spring-cloud-microservice-example but that is more of a framework than an actual application that delivers data.
Not your typical CRUD app but Deis (a PaaS) uses REST APIs mostly to communicate between services. Peatio has a bunch of services that communicate asynchronously through a message queue.
Microsoft provides a demo webshop application based on .NET Core showing how to apply the microservices pattern:
https://github.com/dotnet-architecture/eShopOnContainers
There is also an ebook available: https://aka.ms/microservicesebook
this lagom application example is a microservices application written in Lagom . It is a akka based framework (DDD for design).
Application is complete and working. See if that serve your purpose.
I am trying to get the idea of cloud serves but didn't get the point of that.
Dose it can replace a server for the app?
what is the purpose of it?
I have an android app and I what to get info from the server can it be done with Cloud Foundry and what is spring and how it connects to Cloud Foundry.
If you can give me link of how to communicate android app with Cloud Foundry
thanks a lot!
CloudFoundry's an open-source PaaS (github.com/cloudfoundry). It commoditizes the stack - that is, in practical terms, it makes it dead simple to get things like databases (MySQL, PostgreSQL, Redis, MongoDB), messaging (RabbitMQ), and web servers (Tomcat) up and running quickly. Whereas clouds like AWS let you spin up CPUs and hard disks and a stock OS install, a PaaS like CloudFoundry lets you spin up infrastructure, like message brokers, databases, and web servers and routers. So, yes, it replaces a server (or, often more importantly, it can stand in for 1000 servers on-demand). That's the obvious part.
CloudFoundry itself is open source, so unlike other PaaS solutions, by building on top of CF you're not locked into CF. You can later decide to run the cloud locally on your own datacenter, or on some other CloudFoundry provider (CloudFoundry.com is just one provider of the CloudFoundry software. Just as you can easily re-target a git repisotry to have it point to any remote repository using the git command line tool, you can re-target the CloudFoundry 'vmc' command line tool to point to a different CloudFoundry install.
Spring's a development framework in Java. It's not the only way to consume CF, but I personally think it's quite nice. CF exposes a lot of different technologies for the eager technologist and Spring provides the only comprehensive library set that can handle all those options. Learn one Spring library and the others will feel simialar, and so it's more natural to get started with a new API and technology. In the way that APIs designed with idiomatic Python APIs are said to be "Pythonic," Spring's APIs are cohesive and work nicely together. However, if Java's not your cup of tea (punny!), then that's OK too. CloudFoundry supports Ruby on Rails, Scala, Node.js, and other cloudfoundry providers support alternatives (Stacato supports Python, AppFog supports PHP, etc.)
For a quick example demonstrating how to get started with Spring, and the SpringSource Tool Suite, and a development virtual machine for CloudFoundry (so you can develop locally and quickly), check out this blog (and, particularly, the video embedded therein): http://blog.springsource.com/2011/08/24/micro-cloud-foundry-for-spring-developers/
The Springsource team has been doing some interesting work this year integrating a variety of Spring projects with Cloud Foundry.
With the rising popularity of microservices, many of the Spring projects are proving to be useful not only for quickly developing these smaller, lighter weight services, but also for easily incorporating some of the projects from Netflix OSS that implement patterns for making them industrial strength even at web scale.
A few related links:
The latest Cloud Foundry Java buildpacks include support for Spring
Boot and Spring Auto-reconfig (https://github.com/cloudfoundry/java-buildpack/releases).
The CF docs
contain an example on deploying Spring Boot apps to Cloud Foundry or
Heroku
The new Spring Cloud project will "Integrate your application with Pivotal Cloudfoundry. Makes it easy to implement SSO and OAuth2 protected resources, and also to create a Cloudfoundry service broker."
I look forward to seeing more of the results from the collaboration between the Cloud Foundry and Spring teams. One evidence of this is a recent tweet from Pivotal's James Watters "As the Microservices trends take off its pretty amazing to have the world's leading lightwieght #springframework on same team as CF."
