Alachisoft in TechEd America and TechEd Europe

June 7, 2012

Alachisoft has announced its participation in TechEd America and TechEd Europe to be held in Orland from June 11-14,2012 and June 22-25, 2012 in Amsterdam respectively, according to the Alachisoft Newsletter. Alachisoft will showcase two of its premier products there, NCache and StorageEdge.

Iqbal Khan, The Technology Evangelist at Alachisoft, will demonstrate to the visitors how NCache reduces expensive database trips resulting in enhanced performance and extended scalability, especially since these qualities are now considered core requirements for a reliable and efficient enterprise application.

While StorageEdge promises to strengthen your SharePoint ROI by assisting in offloading BLOBs onto cheaper storage tiers with various filtering options to help improve user experience and bandwidth. Though I’ve discussed the benefits and features of StorageEdge in detail in my earlier post, below are some of the highlights,

    – RBS Filestream provider
    – BLOB Externalization
    – Archiving to multi-Tire Storage
    – Rational Archiving for Compliance
    – File Share linker
    – Database Mirroring
    – Asynchronous BLOB Writing

Visitors will witness these remarkable features and noticed the strength of StorageEdge and NCache via live demos and presentations at the booth, apart from the brochures.

The event, hosted by Microsoft, is the leading event for business and IT professionals from all over the world. TechEd is offering most comprehensive education across Microsoft current and soon-to –be –released suites of products, solutions, tools and services. This will be the 20th Annual TechEd North America this June in Orlando and it will deliver four days of hand –on training from Microsoft experts.

Alachisoft also participated in the Last year’s TechEd which was held in Atlanta, North America. “This helped us build confidence in our customers who see us there every year and projected our growing influence and strategic place among up and coming companies. Thank you to all who were part of it and made it a success” said by CTO Iqbal Khan at the end of the last year’s event.


Compact Serialization Vs .Net Serialization

August 1, 2011

Serialization is the process of converting the state of an object into a form that can be transferred on the wire. The opposite of serialization is deserialization, which converts a stream into an object. In distributed applications the serialization takes place whenever the data has to go out of the process or machine. Serialization in general is a slow process because of the IO and can become a performance bottleneck for distributed applications.

The .NET framework provides multiple serialization techniques such as binary, SOAP and XML serialization. Binary Serialization is commonly used and is much faster than the other serialization techniques. It preserves type consistency, which is useful for preserving the state of an object between different invocations of an application.

Although, .NET binary serialization is fast but it has some serious limitations. When it comes to network, speed of transfer of data is dependent on the data size. When a data is shared process to process while traveling on network, it should be serialized. Whenever an object is serialized, it contains so much Meta data of the object that it becomes very difficult to transfer it on the network. Bigger the object, more time it takes to travel on the network. Serialization uses reflection. Reflection is an I/O process which affects performance badly in case of the applications that uses distributed caching as the size of the serialized objects gets almost double.

Draw backs of binary serialization are:

• Slow reflection

• As the object size gets bigger, it affects the performance and slower network trips.

•People who use distributed caching experience a lot of data transferring which gets slower.

NCache is a distributed caching solution which provides you a feature called compact serialization which can help you fix problem occurring in binary serialization.

Compact Serialization is a process which produces a compact form of serialized object for performance improvement which results in faster network trips. It works by serializing the object in compact in form of data and process. The concept behind the compact serialization is that every keyword/data type is assigned a unique 2-byte type handle by the framework, which lets the deserializer uniquely identify them.
For example, suppose the framework assign a handle 0 to System.Int32. Then the serializer writes the 2-byte handle followed by 4 bytes of object value to the stream. Deserializer reads the handle, finds out the object type, and then creates and gives the object its value.

On other hand the binary serialization writes the complete type information with object data.

How Compact serialization is better than .Net serialization?

• In compact serialization, the serialized object does not contain the complete type information and assemblies. It only contains an object value and a unique 2-byte handle is used as a reference to uniquely identify the type’s details while deserializing an object which reduces the object size.

• Compact serialization also avoids the reflection which also reduces the overhead.

• You don’t need to code.

• It reduces the number of IO operations (minimum or no reflection) which increases performance of the application.

• Faster network trips reduce the cost and improves the performance as the size of the object is reduced.
