management, 3rd party SLA management, 
system monitoring, advice, configuration
The architecture
Design principles
Everything as a service โ€“ In the 
cloud
Low (human) touch business flows
Security and redundancy as a priority
Everything as a service
Bespoke built systems: business 
website, disaster recovery system, test/demo 
system, content management system all 
hosted and backup using a cloud hosting 
company
Software as a service SaaS: email, 
document management, customer 
relationship management, marketing, issue 
management systems all commissioned from 
trusted vendors as a service e.g. company 
domain gmail
Platform and Infrastructure as a 
Service PaaS/IaaS: firewall - network 
and website security and redundancy, system 
monitoring and analytics, website payment 
platform, data backups, remote desktop e.g. 
data backups to Amazon Web Services
Exceptions: accountancy software and 
middleware data flow management software 
are โ€˜in-houseโ€™ bought software โ€“ to make 
them โ€˜cloudโ€™ CTO install and run them on a 
remote desktop so that they are seen as a 
โ€˜cloudโ€™ like services to the client
Low touch business flows
Data Integration: CTO configure 
and manage middleware data integration 
software whichโ€ฆ
Extracts customer information from the 
website an feeds it automatically to the CRM 
system and the accountancy systemโ€ฆ
Extracts payments from the website and 
feeds them into the accountancy systemโ€ฆ
Feeds customer raised issues from the 
website or email to an issue management 
system.
Payment System APIs: the business 
website uses trusted payment platforms for 
customer payment details and processing โ€“ 
the website uses the payment system APIs for 
instant processing
Integrated SaaS: CRM system and 
marketing systems chosen due to their 
compatibility and automatic integration
Security and redundancy as a 
priority
Security: website firewall โ€“ encrypted 
connections, browser checks, IP checks, 
malware checks, denial of service attack 
defence etc
Security: password management by CTO by 
running all your SaaS accounts, configuring 
and monitoring the servers and employing 
strong secure and safely stored encrypted 
passwords
Security: all customer payment details are 
stored and processed by an accredited 
payment platform and not managed by OP or 
CTO e.g. paypal
Redundancy: mirror disaster recovery 
website system โ€“ synchronised, and at a 
separate location
Redundancy: data backed up by webhost, 
data also backed up via middleware to 
Amazon Web Services (AWS) for archive e.g. 
fast recovery and slow recovery
Redundancy: daily accountancy 
interface files stored at AWS for full back-up 
and recovery of accountancy data
Redundancy concerns: currently 
trusting the SaaS providers of the email, 
document management, issue management 
and CRM systems to safely manage the 
redundancy of the data
OP run a fully functioning business and 
do not own or run any hardware or 
software โ€“ outside of employee laptops 
with the basic apple or windows 
operating systems
