Vertical Autoscaling

As your application's resource requirements begin to grow we automatically increase the number of available cloudlets (128 MB RAM & around 200 MHz CPU) ensuring your application performs optimally - up to 32 cloudlets (4GB RAM & 6.4 GHz CPU) per app server! As soon as your resource usage decreases, your cloudlets begin to drop to ensure you are only paying for what you need! Configure a maximum number of cloudlets per application server any time via our Jelastic dashboard and rest assured our system will scale your app up and down in just seconds.

Horizontal Scaling

We understand the importance of your applications being available at all times and so offer maximum flexibility for scaling your application horizontally too. You can scale your application horizontally to increase application availability and resources (up to 16 app servers per environment!) with automated load-balancing to share the load between your instances, high-availability clustering, sticky sessions, and seamless, automated app synchronization between your containers.

Ultimate scalability, flexible topology!

With our most powerful option your application can scale up to 32 cloudlets per instance, and up to 16 instances per environment. This gives you a maximum of 16 app servers with a total of 64 GB RAM, 100 GHz processing power, 8 clustered server pairs with intelligent session replication for high-availability and advanced load balancing - all deployed effortlessly and your deployed applications are automatically replicated.

Usage Based Billing

Every hour we record the resources consumed by your environment and deduct the usage from your prepaid account balance - this means you only pay for the cloudlets, storage and public IP's in the hours you use them. As we autoscale your resources you can be sure that you are paying us for the resources your application needs and nothing more - the only cloud platform around which automatically scales you both up and down! Traffic is billed per GB for the traffic you consumed within the hour. Trial usage is free as long as you remain within your free trial allowance, after which you can easily convert to a paid account without any loss of data!

Effortless Deployment

Don't waste your time deploying applications to inefficient platforms! We make it simple for you to deploy your applications by uploading to our dashboard and clicking 'deploy to environment' to automatically install the app on all of your server instances in seconds.

Need more automated deployment? Using a Subversion or Git repository for development? No problem with full Maven build node integration for your Subversion or Git repos to automatically upload and deploy your applications upon demand.

Your Data Is Safe!

We take backups every 6 hours for rapid data recovery in a disaster.

Use the deployment manager to easily revert your code to an older revision.

With high-availability or horizontal scaling rest assured you have an extra copy of your data stored in our cloud!

Our self-healing data storage ensures no downtime and data security even if we lose up to 5 physical disks per cloud backend server (no unreliable storage here!) and with our on-site staff we can quickly replace any disks to ensure your data is completely safe!

Expecting the Unexpected

Modern websites read and write a lot of data to disk for every website visit. Many hosting providers' intense focus on profits causes them to cut costs on this aspect of their service, but this makes your website slow!

Each of our cloud backend servers is powered by two octo-core Intel® Xeon® CPU's with a total of 32 logical cores, at least 96 GB high speed DDR3 RAM and gigabit network ports to ensure your data is served really quickly at all times.

We exclusively use fault-resistant RAID 60 arrays of enterprise grade high speed disks to give you and your visitors very high performance and very high data redundancy.

If a server is beginning to use a lot of resources we automatically distribute the load by migrating Jelastic instances to other backend servers with zero downtime!

Open Software Stacks

Use your preferred software stack from a wide range of open source application and database servers! We fully support Tomcat 6 & 7, TomEE, Jetty & Glassfish, a wide variety of SQL (MySQL, MariaDB, PostgreSQL) and NoSQL (MongoDB, CouchDB) database servers working seamlessly alongside your favourite Maven and Ant tools.

Full layer 7 load-balancing, reverse HTTP proxy and caching is provided by the high performance NGINX web server which is automatically installed and configured for you if selected.

Zero Vendor Lock-In

Unlike most of our competitors, we can run ANY application without changes to your code. You don't need to code to complex development API's (we don't have any!) or write code within inflexible system constraints.

UK Hosted, Well Connected!

Our Jelastic Cloud is locally hosted in our UK-based datacentre with direct links into regional and international network operators, major Internet backbone networks, and key Internet exchanges. This super fast and reliable network connection between your website and visitors is essential to your conversion rate.
