The service
Our approach to High Availability & Cloud Architecture
Downtime directly impacts your bottom line. We architect and maintain high-availability environments deployed in tier-rated data centre facilities equipped with redundant power, multi-homed carrier feeds, and automated failover capabilities. By eliminating single points of failure, CreateITivity ensures your systems and digital services remain accessible 24/7/365 to clients and team members across Canada.
Problems that show up again and again when we first look at an account. Our plan is built to deal with each one.
One carrier outage takes you offline
Your systems depend on a single internet provider. When that provider has a bad day, staff in the office and customers on your portal are cut off together.
A whole region down, and you with it
Everything runs in one data centre or one cloud region. A power, cooling or network event there means a full outage, however well the servers themselves were set up.
Failover that depends on a phone call
There is a standby system, but switching to it means someone has to notice the problem, wake up and follow steps that have never been rehearsed.
Maintenance means a "back soon" page
Patching or upgrading the database takes the service down. For a business with clients in several time zones, there is no good hour to be offline.

How we keep the work accountable
Before work starts, we agree on the number that matters most to you. Each sprint is planned against it. You get a short recorded update every week and a dashboard you can open any time, and the senior lead joins every call.

Our Process
Four stages of High Availability & Cloud Architecture
The same order every time: find the constraint, plan, deliver, then review. Here is what each stage involves.
01
Trace the failure points
We follow the path from user to data and list every component that would cause an outage if it failed, ranked by business impact.
02
Design the redundancy
Duplicate what matters, decide where the second copy lives and set how quickly each system must recover. All of it is agreed with you before anything is built.
03
Build and replicate
Standby systems, replication and automated failover go in alongside your live environment, so the service keeps running while it is made resilient.
04
Test failover regularly
We trigger failover on a schedule, check it behaved as designed and send you the results.
01
Impact by layer
The design starts with the failure that would cost most
Finding the weak points
Map every single point of failure first
Redundancy only helps where the failure actually happens. We trace a request from the user to the data and back: DNS, the carrier link, firewalls, load balancers, application servers, databases, storage and the third-party services you call. Each layer is checked for what happens if it disappears.
The result is a ranked list of single points of failure, from the ones that would stop the business to the ones that would only slow it down. That list drives the design, so effort goes where an outage would cost you most.

02
Replication between regions
Primary and standby kept in step
Redundancy at every layer
Two of everything that matters, in more than one place
Our high-availability environments run in tier-rated data centres with redundant power and multi-homed carrier feeds, so the facility itself is not the weak link. Above that, we duplicate what the assessment flagged: application servers behind a load balancer, databases replicated to a standby, storage mirrored and, where the business needs it, a second region ready to take over.
For organizations that must keep data in Canada, both regions can be Canadian, for example one in the Toronto area and one in the Montréal area, so redundancy never means data leaving the country.

Failover you have seen work
Automated failover, tested on a schedule
Failover has to happen without a person in the loop. Health checks watch each component, and when one stops responding, traffic and workloads move to a healthy copy automatically. The same automation lets us take nodes out of service for patching while the others carry the load, which is how planned maintenance stops meaning planned downtime.
We test failover on a schedule agreed with you, record how it went and fix anything that did not behave as designed. You get the results in writing, which also helps when insurers, auditors or clients ask how you handle outages.

FAQs
Before you sign: common questions
Straight answers on scope, timing and how we report.
What is the difference between high availability and disaster recovery?
High availability keeps a service running through a component or site failure, usually by switching automatically to a live copy. Disaster recovery restores systems after a larger event, from backups or a recovery site. Most businesses need both; our backup and disaster recovery service covers the second part.
Do we need a second region?
Not always. Redundancy inside a single tier-rated facility protects against server, storage and network failures. A second region protects against losing the whole site. We base the recommendation on what an outage would cost you and how long you could tolerate one.
Can both regions stay in Canada?
Yes. Where your data must stay in the country, we design with both the primary and the standby in Canadian locations, such as the Toronto and Montréal areas, so failover never moves data across the border.
Can you make our existing system highly available?
In many cases, yes, though older applications sometimes need changes before they can run on more than one server. We assess the application first and tell you what is possible as it stands and what would need development work.
How do we know failover actually works?
We test it. Failover is triggered on a schedule agreed with you, the results are recorded and anything that did not behave as designed is fixed and retested. You receive a written summary each time.
Find the weak spots in your systems before they fail
Tell us what you run, where it is hosted and what has gone wrong lately. One of our engineers looks it over by hand and sends back the first fixes we would make, whether or not you hire us. Marketing and development questions are welcome too.
Tell us about the business and a senior specialist will get back to you within one business day. If starting with managed hosting looks like the wrong first step, we will say so and suggest what to fix first.
