Session Replication

Session replication is a mechanism used to replicate the data stored in a session between different instances which are part of the same cluster. When session replication is enabled in a cluster environment, the entire session data is copied on a replicated instance.
Session replication provides high reliability, scalability, and failover capabilities.

Automatic Scaling Within and Across Servers

LWS dynamically allocates granular units of resource to applications called “Cloudlets”. Each cloudlet represents 128MB RAM and 200MHz CPU.
LWS automatically scales resources up and down within a single server or across multiple servers based on the application load.

Save Resources and Money

The Luxembourg Web Services fully elastic scalability means that server utilization is significantly increased, with at least 30% improvements in density. LWS users have saved up to 73% of server resources and cost when compared to solutions that allocate fixed VMs or large blocks of resource.

Simplified Management

The  Dashboard creates and manages the application environment including application servers, load balancers and clustering and availability.
Keeps server configurations up to date and consistent across the environment
Defines parameters for auto-scaling applications
Provides orchestration for application deployment, patches, updates and roll-backs

Horizontal Scaling

An application can be scaled across multiple servers with horizontal scaling and load balancing.
Applications can be pre-configured to scale across multiple servers via the user interface. When additional server nodes are defined, load balancers are automatically configured and activated to distribute the application load.
Application instances can be configured for maximum performance and availability using horizontal scaling.

1- Set up in second your cloud environment

Choose your software stack, set the limits for auto-scaling and pick your name. In just a few seconds your environment will be up and running.
Mix and match from Tomcat, Glassfish, Jetty, Apache, NGINX application servers, as well as SQL (MariaDB, PostgreSQL, MySQL) or NoSQL (MongoDB, CouchDB) database servers.

2 – Upload your standard Java, PHP, Ruby, Node.js or Python App – no APIs to code to

Unlike other PaaS offerings, Luxembourg Web Services does not require any changes to your application. No complex APIs to code to.
LWS automatically installs, configures and interconnects your server instances with your selected software stacks. No configuration or installation required.

3 – Set up automatic scaling and HA

It’s elastic scaling. If an application load grows, we allocate more resources (RAM and CPU). When load goes down, we release those resources—automatically.
LWS also automatically load balances across nodes if you choose multiple instances.

4 – Enjoy your App and make business !

Choose you app in the marketplace or upload your app package and  to your LWS environment. If there are multiple instances, we will update all of them – automatically. Use GIT or SVN for deployment ? We support them both, so if you have any changes to your code, deploy them in one click !
