This section contains three categories to provide a little more clarity on the terms terms that crop up in the world of cloud computing.



Value Proposition for Cloud Computing – Legal

There are many reasons for choosing cloud services as part of an IT strategy. Not all of the benefits given below are relevant in every case but businesses will make decisions based on the relevance of each to their business model.

New technology or technology refresh – many start-ups require significant upfront capital spend in technology and established businesses must maintain existing infrastructure which requires on-going investment – e.g. servers, pcs. Cloud removes this capital cost.
Predictable running costs – In the traditional IT model, you have to spend money upfront on the infrastructure for any new technology. Not so with the cloud, where (just like renting a car or buying electricity) there’s no infrastructure or capital cost. Since you pay per-month, per-user, you can budget for a predictable spend over any given time frame.
Scale up, scale down – Cloud allows firms to scale up and down as need demands. A law firm for example may require significant extra staff when dealing with a large case and cloud allows the flexibility of scaling up to meet this demand and scaling back down when the extra resources are no longer required.
The IT headache – the idea of removing servers and related technologies from on premise to cloud is very attractive to many firms as it gives all the benefits of a data centre model – high availability, security, server management, patching etc. – without the need for in-house IT resources. Cloud services are certainly far more robust than anything any small to medium-sized businesses could reasonably afford acting unilaterally.
Level playing field – traditional IT strategy required implementation of sophisticated and expensive solutions which for many firms went way beyond their financial capacity. Cloud breaks down this barrier by making even the most sophisticated applications available to all at a fixed monthly charge. The cost of a full blown Practice Management System can have prohibitive upfront costs but in the cloud, all the benefits of such a system are available on a much more manageable basis.
Speed to market – for those in the business of innovation, speed to market can be the difference between success and failure. Many firms are heavily dependent on technology to deliver new products and being able to tap into cloud based platforms significantly reduces delays and upfront capital costs.
Mobility –Cloud services are by definition available to the mobile workforce, anytime anyplace, anywhere.
24/7/365 – the cloud never sleeps.
Backup and Disaster Recovery – cloud infrastructure is far more resilient with data replicated to second sites in many cases and represents a built-in backup and disaster recovery option.

Cloud computing costs will vary from one firm to another and between one provider and another but the option to write off costs as part of operational expense is very attractive for many firms. It is clear however that for many others the value proposition is about much more than cost savings.

usually expressed as a percentage, e.g. 99.95%

personal data
information relating to an identified or identifiable individual that is recorded in any form, including electronically or on paper

Lex Cloud Questions Answered

Q Where is Lex Cloud hosted

Our hosting facility is in a Data Centre in Dublin run by Interxion, one of Europe’s leading data centre operators.

Q What level of accreditation does the  data centre have

It is certified to ISO 27001 the highest  level attainable. The centre operates 24/7/365 with security staff on duty at all times.

Q Who can enter the data centre

Only authorised staff are allowed into the facility and must present primary ID at all times – i.e. passport or driving licence.

Q What other security measures are in place

The data centre has independent power and backup generators as well as fire suppressant Halon Gas with an air lock entry system. You will find more details here.

Q Who owns the cloud infrastructure

We are one of the very few cloud providers in Ireland who both own and operate their infrastructure as many ‘cloud providers’ use third party clouds that may not be hosted within this jurisdiction.

Q Who has access to the data hosted on our cloud

Only the client has access to his/her data. We as the service provider will interact with the client to provide support and backup of your data for which we need the requisite access permissions. From time to time, we may use third party consultants for specific projects but they are always supervised by Prosalis staff. Anyone working on our behalf must also sign a non-disclosure/confidentiality agreement. In the case of LexCloud which is a joint initiative with Documatics and support for the LE application itself is provided by the Documatics team.

 Q How frequently are backups taken

In the case of LexCloud backups are taken several times during the day to minimise any data loss interval for the client. Our backup cycle runs for 30 days so it’s possible to recover files that might have been lost within that window. It should be noted however that Legal Evolve, the Practice Management application behind LexCloud makes it very difficult for files to be lost or deleted accidentally.

Q Must I use Legal Evolve as my Practice Management System

LexCloud is a trading name for Prosalis and the cloud environment is managed jointly with Documatics who developed the Legal Evolve suite of software, one of the leading PMS brands in Ireland. We have a good working relationship with Documatics and LexCloud has been very successful. Together with the other application hosted alongside Legal Evolve, Office 2013, Outlook and Dictation software, it offers a very compelling proposition for the legal profession. if it doesn’t quite fit your needs please see answer to next question.

Q Can I run my own suite of applications in your cloud environment

Yes. Some of our clients have existing on premise solutions with a heavy investment and remain committed to them. In this scenario, we can create a virtual private cloud (VPC) and migrate the client’s on premise applications. Thereafter the client simply connects to our cloud and operates all systems from there. The Microsoft Office suite is already available on our cloud and is licensed under our Microsoft Service Provider Agreement.
