Using Empress Embedded
Database with Cloud Computing
Introduction
Empress Embedded Database v10.20 has many features, including
replication and encryption that are well suited for usage in Cloud
Computing and SaaS applications.
Cloud Computing is a ground-breaking technology that promises benefits for the companies who deploy it. Rapid scalability on
demand, access anywhere, easy upgrading to the next version, low
or no system and network administration are among only few of the
benefits. Cloud Computing can be deployed as an Infrastructure as
a Service, Platform as a Service or Software as a Service model.
Software applications when used in Software as a Service (SaaS)
cloud service model are not desktop applications but web
applications that they can be used by any web browser. Typical
examples are accounting, financial management, inventory,
e-commerce, customer relationship management (CRM) applications.
Most of these Cloud Computing software applications benefit from a
database management system as a storage mechanism.
Using Empress Database in the Cloud
Empress Database can be used in the cloud in many different ways.
A typical example is a web browser accessing a web server in the
cloud that uses Empress Database as a storage mechanism via one of
the web database technologies such as PHP.
Another way of deploying Empress Database is by running Empress
Connectivity Server in the cloud. Then the client application can
use any of the standard database interfaces (APIs) such as
ODBC/JDBC to access Empress Database in the cloud.
Both the web server and connectivity server are shown in Figure 1
below.

- Empress database may contain terabytes of
data. Hence it is a good choice for those applications that
deal with large amounts of data.
- Empress Database is well known for
accessing data very fast (doing insertions, updates, deletions
and retrievals).
- Empress has encryption and replication
features.
- Empress Database is very cost effective.
In the following text we will emphasize encryption and replication
as Empress features that can be efficiently used in the cloud.
Data Protection Risks – Empress Encryption is a Solution
The following are the main benefits of using Empress Encryption in
the cloud:
- Selectively secures database data.
Protects selected user data in a database including logs and
backup files.
- Efficient security solution. Low
performance overhead on encryption & decryption with
minimal database size increases.
- No need for application code changes. No
change is needed to existing cloud web applications compared
to an unencrypted Empress database.
- No external stuff needed for the
database. To enable encryption Empress does not require
additional stored procedures, triggers, views, etc.
Empress encryption is painless for users who choose to convert
their non-secure cloud database solution to a secure one.
Empress Replication Cloud Solution
Empress Replication allows users to hold either the master
database, replica database or even both in the cloud.
Some of the more important benefits of using Empress Replication
are:
- Higher data availability
- Reducing network traffic by using a
local copy of data
- Off-loading data contention between
database applications
- Distributing system load across multiple
locations
- Easy recovery from system failures
- Automatically providing data copies
through a network
Empress Replication can be set to replicate only subsets of data.
If needed. Empress Replication can use a secure communication
channel to synchronize data between master and replica databases
as shown in Fig. 2.
Two examples of Empress Replication Cloud deployment are shown in
Fig. 2.

Quick Recap
Empress Embedded Database has many features suited for usage in
the cloud.
- Fast performance
- Large data set management
- Encryption
- Replication
- Cost effective solution
