L. STATUS AT THE END OF COPERNICUS 1 
As described in the previous chapter, the CIS proved to be 
a robust system. This aspect of the system must be kept 
for the future of the Copernicus Marine Service. 
The main challenge has been to implement changes over the 
course of time. All those evolutions came at a price: the Data 
Portal and the Viewer were built usina 2008 technologies that 
are now outdated (if still supported). In 2019, it was been 
decided that the technical debt was too high to be managed 
and that a full rewrite of the Data Portal and the Viewer must 
take place. In the same spirit, the authentication services 
zould benefit from some additions that are now more widely 
used than the one used in the Copernicus Marine Service 
(OpenID or OAuth instead of CAS). 
Globally, the whole CIS architecture is still the same ir 
2021 (Figure 10), but many pieces have been removed or 
absorbed bv modern technology capabilities.
